Leave it to Jimmy Fallon to bring together some of the biggest stars in Hollywood for his first episode as host of "The Tonight Show."
On Monday night (Feb. 17), Fallon was joined by more than a dozen A-list celebrities who each ponied up the $100 they owed him after losing a bet that he'd never host the "The Tonight Show."
Robert De Niro, Tina Fey, Mariah Carey, Tracey Morgan, Seth Rogan, Lindsay Lohan and Lady Gaga were among those in attendance, and Kim Kardashian has the backstage photos from the historic night.
"You guys watching Jimmy Fallon tonight? Fun behind the scenes pic with these funny guys, Seth Rogan & Tracy Morgan," the 33-year-old reality star wrote along with a photo of the two funnymen, sharing a larger group photo as well.
