Celine Dion and the Jonas Brothers joined the chorus of mega-stars gathered to remake the classic anthem "We Are the World."
75 of the biggest names in music, including Barbra Streisand, Kanye West, and Jennifer Hudson, stood shoulder to shoulder in the packed studio for hours, recording the song to raise millions for earthquake-ravaged Haiti
"I'm excited to be here," said Jennifer Hudson as she entered the studio.
Stars like Jamie Foxx, Tony Bennett, Jeff Bridges, and Snoop Dogg were all smiles arriving at the studio, the same studio where the original "We Are the World" was recorded 25 years ago.
"Those people are going through tough times, it's great that we can all gather and be together and support them as much as we can," Celine Dion told INSIDE EDITION.
"I am very excited, I'm honored that Quincy Jones asked me to be a part of it," said LL Cool J.
Barbra Streisand, famous for her perfectionism, "recorded her solo over and over" while everyone else took a dinner break.
And who knew Vince Vaughn could sing? He was part of the star-studded ensemble and was photographed joking around with Harry Connick Jr.
Nicole Richie's husband, Joel Madden, bounced to the music while holding their 2-year-old daughter Harlow. She was there to cheer on her grandfather, Lionel Richie.
Richie, who co-wrote "We Are the World" with Michael Jackson, helped organize the remake. And the 2010 recording was produced by music mogul Quincy Jones, who also produced the original in 1985
Janet Jackson will be digitally added in at a later date. She's paying homage to her late brother Michael by recording his famous solo from a remote location
"It was magic in there, it's hot, sweaty, and we've been standing there for a little while but what's funny is it's kind of become like a bonding, we're all here for a great cause," Josh Groban told INSIDE EDITION.
And Brandy said, "It was beautiful energy, positivity just to be part of something so great."
