Comedic actor Kevin Hart took to Instagram on Monday (August 28) to implore his celebrity friends to be a part of his Hurricane Harvey Relief Challenge, including JAY-Z, Beyoncé, Chris Rock and Dave Chappelle.

“I’m calling this the Hurricane Harvey Relief Challenge,” Hart wrote in the caption. “Lets go @therock @beyonce @chrisrock Jay Z Dave Chappelle @jerryseinfeild @iamsteveharveytv @justintimberlake #HurricaneHarveyReliefChallenge #prayforhouston …..I am getting a link together now people. Help me help Houston.”

Among those who have answered Hart’s call are T.I., Nicki Minaj, Chris Brown and DJ Khaled.

The Rock also informed those on the ‘Gram of his decision to donate $25,000 to The Red Cross.

In a statement released to The Houston Chronicle on Tuesday (August 29), Beyoncé shared her plans to join the cause.

“I am working closely with my team at BeyGOOD as well as my pastor (Rudy Rasmus at St. John’s in downtown Houston) to implement a plan to help as many as we can,” the statement read.

According to TMZ, the Kardashian family has also donated $500,000 to relief efforts, which has been distributed to The Red Cross and The Salvation Army.

Meanwhile, Lil B is donating verses to any artist affected by Hurricane Harvey, but it’s unclear if it was prompted by Hart’s plea.

And although he’s currently overseas, Drake is also working with relief organizations in Houston.

It’s been days since Hurricane Harvey made landfall in Houston and other cities in Texas, but flooding in the area continues as more rain heads to the state.

In addition to The Red Cross, Hurricane Harvey Relief Fund and the Houston Food Bank are among the organizations also accepting donations.
