Jimmy Fallon Impresses With Star-Studded 'Tonight Show' Debut

Jimmy Fallon took the helm of the Tonight Show last night in a star-studded debut that marked the show's return to New York City after more than 40 years in LA. The newbie's guests included Will Smith and U2 — who performed new song "Invisible" on the roof of Rockefeller Center — but big names including Robert De Niro, Joe Namath, Rudolph Giuliani, Lindsay Lohan, Lady Gaga, Mike Tyson, Joan Rivers, Stephen Colbert, and Sarah Jessica Parker also turned up to plunk $100 on Fallon's new desk after Fallon joked about winning a bet from a "buddy who said that I'd never be the host."
