Want to sit on the "Friends" iconic Central Perk couch?

Jennifer Aniston is offering six lucky superfans the chance to join her and her co-stars – Courteney Cox, Lisa Kudrow, Matthew Perry, Matt LeBlanc and David Schwimmer – at their upcoming HBO Max reunion special.

The once-in-a-lifetime opportunity is part of the charity fundraiser the "All In Challenge," which is spreading through Hollywood amid the global devastation caused by the coronavirus.

"We’re inviting you and five of YOUR friends to join the six of us on Stage 24," Aniston wrote on Instagram Tuesday. "Be our personal guests in the audience for the taping of our @HBOMAX reunion, as we reminisce about the show and celebrate all the fun we had... and get the whole Friends VIP experience on the Warner Bros. Studio Tour."

'Friends' reunion officially happening with HBO Max special; Jennifer Aniston, cast reuniting

The money raised through the challenge will go to various charities, including Meals on Wheels America, No Kid Hungry, World Central Kitchen, Feeding America and America's Food Fund.

The taping of the much-awaited reunion of the six "Friends" cast members, previously scheduled for March 23 and 24, was postponed, a source with knowledge of the matter but not authorized to speak publicly confirmed to USA TODAY on March 18. Taping of the unscripted special is now supposed to happen at a later date on the "Friends" stage, Stage 24, at Warner Bros. Studios in Burbank, California.

The "Friends" cast members aren't the only screen and sports stars auctioning unforgettable experiences to feed families suddenly in need.

Gwyneth Paltrow is auctioning off some Oscars glam for a good cause.

The "Shakespeare in Love" star took to Instagram on Friday to share that she will be auctioning off something that "holds great sentimental value": the hand-beaded Calvin Klein dress she wore to the 72nd Academy Awards in 2000.

"It's very end of the 90s, which is back in style now," Paltrow said of the dress, which she pledges to hand over to its new owner in person. "So I thought it would be a good one to donate."

On Monday, Ryan Reynolds and Hugh Jackman joined the challenge, announcing on Instagram they will put aside their joke "feud" for the greater good.

"For one day, and for one day only, we've agreed to agree to not disagree," Reynolds said. "And only a pandemic could make that happen."

The winner of the pair's sweepstakes will have the two actors fly to their home to set up a lemonade stand with their kids.

"I’ve agreed to trust that Ryan can hold his tongue for one day," Jackman wrote on Instagram. "A (very) temporary cease-fire for the @allinchallenge."

Madonna also got in on the challenge Friday, sharing in an Instagram video that the pop star will be auctioning off a coat from her Madame X Tour for charity.

The jacket will come with a personalized autograph, and Madonna will sing "Happy Birthday" on the phone to the new owner for their birthday. She passed the challenge along to Ariana Grande.

Leonardo DiCaprio and Robert De Niro are also making fans an offer they cannot refuse — a walk-on role in their next Martin Scorsese-directed movie, "Killers of the Flower Moon."

"If you have ever wondered what was like to be able work with the great Martin Scorcese, this is your chance," DiCaprio said in a joint video with De Niro posted on Instagram Wednesday.

"And you'll be able to spend the day on the set with the three of us," said De Niro. "And, of course, you'll attend the premiere."

The “All In Challenge” was started by Philadelphia 76ers minority owner Michael Rubin on Tuesday. Just 24 hours later some of the biggest names in sports and entertainment had answered the call.

DiCaprio said 100% of their proceeds from the auction will go to America’s Food Fund, along with No Kid Hungry and Meals on Wheels "to make sure every family in need gets access to a meal at this critical time."

DiCaprio passed the challenge onto Matthew McConaughey and Ellen DeGeneres, while De Niro challenged Jamie Foxx, who offered a walk-on opportunity on the set of his new Netflix show with his daughter Corinne.

McConaughey immediately posted on Twitter that he had accepted the challenge. "Matthew McConaughey is all in," he said, offering the opportunity to spend the afternoon with his family and friends at a University of Texas Longhorns football game. He threw out a challenge to Jonah, who offered a day watching him direct an upcoming film, and Jimmy Kimmel, who offered a sit-in with the band of “Jimmy Kimmel Live!"

DeGeneres tweeted a video that offered a chance for a fan to co-host her show and personally donated $1 million to hunger charities. She passed the challenge onto Laura Dern and Justin Timberlake, who offered a chance to play golf and have dinner with him and Bill Murray.

And so on.

By Wednesday, the list of accepted challenges included Tom Brady (who offered tickets to the home opener for his new NFL team, the Tampa Bay Buccaneers), Peyton and Eli Manning; musicians Justin Bieber, Meek Mill and Robin Thicke; Kevin Hart and Ryan Seacrest; TikTok stars Charli and Dixie D’Amelio; basketball Hall of Famer Magic Johnson; Chicago Cubs infielder Anthony Rizzo and retired baseball star Alex Rodriguez; and several NFL, NHL and NBA teams.
