Fallon

Believe it or not, there actually was a good reason for him being there.

It looks like he was having a blast!

The sometime MAC collaborator tells 'Elle' why Mariah's "all about Mimi," while Miley's art "isn't about me" — and that she'd never be caught selling makeup.

According to Kelly, she and Jimmy 'have chemistry.'

Gwyneth Paltrow and Jimmy Fallon sing real, awkward failed text flirts on 'The Tonight Show.'

The album consists of eight untitled and unmastered tracks that didn’t make it onto last year's incredible 'To Pimp A Butterfly.'

We’ve seen Jimmy Fallon take on the likes of Breaking Bad, Game of Thrones and House of Cards, but with Empire Season 2 drip-dropping its FOX premiere tomorrow night, Fallon was bound to take the throne. Watch the real Cookie and Lucious chime in as The Tonight Show takes on the Empire with Jimpire!

Justin Timberlake and Jimmy Fallon just did the opening monologue for 'SNL's' 40th anniversary special and, of course, it was insanely epic.

The SNL 40th Anniversary Special started off like you thought it might with two of its most popular modern day partners, Jimmy Fallon and Justin Timberlake. The two took the stage for the show's cold open and sang, danced and rapped their way through 40 years of SNL history (with a few special guests, of course).

Thank goodness for iPad apps. On last night's 'Tonight Show,' host Jimmy Fallon -- who grows more California by the minute, as the show has temporarily relocated to the West Coast -- and guest Will Smith decided to finally give the people what they want: rapping. Well, sort of.

Like many of us, 'Tonight Show' host Jimmy Fallon appears to believe that Hollywood superstar Bradley Cooper can do anything -- and, based on his impressive resume of stage and screen roles and accolades, the guy can't be too off the mark. But there is one that Cooper isn't so great at: music. It's sort of surprising, really, and even the overly solicitous Fallon was a little dumbstruck when Cooper admitted that his musical talents are minimal on last night's show.

Jimmy Fallon and Justin Timberlake are pals. Like, serious pals. These guys make Apple commercials together, which is a true mark of friendship if there ever was one. On last night's 'Tonight Show,' the duo decided to team up for another round of, well, just whatever the heck it is these two do together.
