Celebrities led by Sandra Bullock on Wednesday poured millions of dollars into relief efforts after monster storm Harvey ravaged Houston.
Bullock, who maintains homes in nearby Austin and New Orleans, donated $1 million through the American Red Cross, the organization said.
"I'm just grateful I can do it," Bullock, the star of Hollywood hits such as "Gravity" and "The Blind Side," said in a statement.
Socialite Khloe Kardashian said that her celebrity clan was donating $500,000 to the Red Cross and the Salvation Army.
She was responding to a challenge set by the comedian Kevin Hart, who on Tuesday said he was donating $25,000 and named celebrities whom he urged to follow suit.
In response, pop star Jennifer Lopez and her boyfriend, baseball legend Alex Rodriguez, in a joint Instagram post said that they were each donating $25,000.
"Seeing these pictures of children and all the footage, it's just devastating, and we just want to do our part to help," Lopez said.
Rapper Nicki Minaj, hip-producer DJ Khaled and actor and wrestler The Rock were among other celebrities to respond to Hart's challenge and donate $25,000.
The Rock urged Houston to stay strong and thanked Hart but, in perhaps an indirect criticism of the comedian's name-shaming, said he was "not going to call out my celebrity friends -- you guys already know what to do" and urged small donors to come forward with "a buck or two."
Chris Brown, the R&B singer infamous for his legal troubles, told Hart he was donating $100,000 but without explanation said his money "will go to the people" as he was skeptical of the Red Cross.
The country singer Chris Young also said he was donating $100,000 and urged fans to join him.
One of the most successful fund-raising efforts came from football player J.J. Watt, a local transplant who plays for the Houston Texans.
After his online appeal quickly met his goal of raising $500,000 in donations, he repeatedly upped the challenge. By Wednesday he had raised $6 million and was seeking $10 million.
Beyonce, one of the top stars to emerge from Houston, and hip-hop mega-star Drake, who has a home in Houston, have both said they are working on generous relief plans but have not yet revealed the details.
Photos of Madame Tussauds latest Beyonce waxwork have surfaced on social media - but fans are confused by its likeness.
The new wax figure is currently being exhibited at Madame Tussauds in New York, but it's got members of the Beyhive around the world talking.
They're saying the waxwork doesn't resemble the 35-year-old singer and questioning who commissioned it.
Some fans are accusing the museum of whitewashing Beyonce's image.
Picture's of the figure started doing the rounds on Twitter on Tuesday night.
And while some Beyonce fans are loving the latest addition to Madame Tussauds, others are questioning whether the statue is even Beyonce.
Twitter users have been listing stars they think the statue resembles more, including American conservative political commentator Tomi Lahren, Mariah Carey, Britney Spears and Lindsay Lohan. We contacted Madame Tussauds for comment on the release of the statue and here's what they had to say.
"At Madame Tussauds, our talented team of sculptors take every effort to ensure we accurately colour match all of our wax figures to the celebrity being depicted," they told Newsbeat.
"Lighting within the attraction combined with flash photography may distort and misrepresent the colour of our wax figures which is something our sculptors are unable to account for at the production stage."
Beyoncé released the first picture of her one-month-old twins on Friday.
In a post on Instagram, the singer is shown holding the babies and also confirmed their names.
Her girl is called "Rumi Carter" and her boy "Sir Carter," ending the speculation.
Earlier this month, the pop diva and her husband, the rapper Jay-Z, whose real name is Shawn Carter, filed for the copyright of the names, ensuring no one else profits from the names to sell anything from fragrances to music.
Their filing with the US Patent and Trademark Office comes from an identical California address to an application for the name of the couple's five-year-old daughter, Blue Ivy Carter.
Rumi is the name of the 13th-century Persian poet who endures as one of the best-loved writers of the Sufi spiritual tradition, with verses that celebrate love, joy and tolerance.
The choice of "Sir" is less obvious, although the two names raise speculation that both children are boys.
Within minutes of posting the photogram on Instagram, it trended on social media, with fans congratulating the singer.
Rapper Jay-Z is known for drawing a thick curtain over his private life.
But after a four-year gap, the artist has bared himself like rarely before on his new album.
He apologises to his wife, superstar Beyoncé, for cheating and pours out his love for his mother, whom he reveals to be lesbian, all while taking familiar but timely shots on the politics of race.
The 13th studio album by the rapper born Shawn Carter, 4:44, came out Friday as an exclusive on his upstart Tidal streaming service, whose new part-owners, telecom provider Sprint, are banking on the release to woo customers.
Jay-Z - who has restored his name's hyphen - delivers a long-awaited public reply to Beyoncé who chastised him for infidelity on her acclaimed Lemonade album a year ago.
"I apologise / Our love was one for the ages and I contained us," Jay-Z raps over a brassy Gospel refrain.
"What good is a ménage à trois when you have a soulmate? You risked that for Blue?" he asks rhetorically, referring to the couple's five-year-old daughter Blue Ivy.
Beyonce recently gave birth to twins, her father revealed on social media, although the family has yet to confirm details.
On the album, Jay-Z suggests they conceived the twins naturally.
Discussing the album on iHeartRadio, he said 4:44 was named for the time of morning when he woke up and wrote the song.
He and Beyoncé have matching ring-finger tattoos of the Roman numeral "IV" - four being the day in different months of their wedding and both their birthdays.
Embracing lesbian mother
Jay-Z, who recently became the first to rapper to be inducted into the Songwriters Hall of Fame, infuses the album with touches of house music and reggae, giving a sleeker, contemporary sound to the artist whose later albums had veered into mainstream pop.
On the soulful "Smile," Jay-Z for the first time confirms hushed rumours that his mother is lesbian, explaining how she turned to substances to cope with the stigma.
"Mama had four kids but she's a lesbian / Had to pretend so long, that she's a thespian," raps Jay-Z, who has spoken of how his father's absence contributed to his troubled youth in public housing in Brooklyn.
"Don't matter to me if it's a him or her / I just want to see you smile through all the hate," he raps.
"Smile" opens with a snippet from Stevie Wonder and closes with a poem by Jay-Z's mother, Gloria Carter, who recites, "The world is changing and they say it's time to be free / But you live with the fear of just being me."
Jay-Z, like many rappers of his generation, employed homophobic slurs in his early music but was also one of the first prominent voices in hip-hop to speak out in favour of gay rights.
Jay-Z, who alongside Beyoncé campaigned for and became friends with former president Barack Obama, takes on race relations on "The Story of O.J." and "Moonlight" as he concludes that African Americans will invariably be judged by their colour.
"We stuck in La La Land / Even when we win, we gonna lose," he quips about this year's Oscars mix-up in announcing best picture.
Jay-Z elsewhere throws veiled barbs at other rappers including onetime protégé Kanye West, who last year ranted against Jay-Z and in support of then president-elect Donald Trump before entering a hospital.
Jay-Z has especially harsh words for the estate of pop icon Prince, a longtime rebel in the music industry who had signed a deal with Tidal shortly before his death.
The rapper denounces the "greedy bastards" who have commercialised Prince with moves such as bringing his catalogue onto leading streaming service Spotify.
"I'm surprised you ain't auctioned off the casket," Jay-Z inveighs.
But Jay-Z's mind on 4:44 is more on his own "legacy" - which is the title of the last song in which the 47-year-old addresses his children, vowing that the family's fortune and philanthropy will outlive him.
"I'd like to see a nice peace fund / Ideas for people who look like we / We going to start a society within a society."
American pop star Beyonce has given birth to twins, according to media in the US.
Entertainment Weekly, Us Weekly and People magazines confirmed the news, but the date of birth and gender of the babies are not yet publicly known.
Beyonce, who is married to rapper Jay-Z, announced her pregnancy in an Instagram photo in February - the most-liked post in history on the network.
The couple already have a daughter, Blue Ivy, aged five.
There has been no official confirmation of the birth from Beyonce and Jay-Z themselves.
Other photos Beyonce posted after her pregnancy announcement showed her swimming under water, reclining on a bed of roses and sitting naked on a floral throne.
In one, the 'Lemonade' singer stood naked, cradling her belly with one hand and a breast with the other, next to the sculpted head of an Egyptian ruler.
Speculation about the twins' birth had grown in recent days after a woman was photographed entering a Los Angeles hospital on Friday holding a card that read "B + J".
Beyonce is the most-nominated star in the history of the Grammy awards, and her album Lemonade was the world's best-selling record of 2016.
She had been due to headline the Coachella music festival in California in April, but pulled out on her doctor's advice.
The twins' birth - if confirmed - comes only days after actor George Clooney and his wife Amal welcomed their own set of twins, Ella and Alexander.
