Tina Fey, Lady Gaga, and More Celebrities Who Didn't Believe in Jimmy Fallon

Jimmy Fallon has a lot of friends in Hollywood, but it turns out many of them didn't believe he would ever make it to The Tonight Show. Good news for us: all of them stopped by Fallon's very first show to pay their respects . . . and the $100 they lost betting against Fallon. The parade included Robert De Niro, Tina Fey, Mariah Carey, Tracy Morgan, Joan Rivers, Kim Kardashian, Seth Rogen, Lindsay Lohan, Sarah Jessica Parker, Lady Gaga, and finally, Stephen Colbert with a bucket full of pennies and an announcement: "Welcome to 11:30, b*tch." Have we learned our lesson? Don't bet against Jimmy Fallon.

In case you haven't watched yet, "The Evolution of Hip-Hop Dancing," starring Will Smith is also worth a watch!
