Jimmy Fallon

It's Jimmy Fallon's Lip Sync Battle - 'The Voice' edition!

On her new album, 'Partners,' Barbra Streisand teams up with some of the greatest voices in music. Her latest duet "partner"? Jimmy Fallon!

Dear Hugh Jackman, you know that 'The Tonight Show' is on television, right? More specifically, it's on live television in front of a studio audience, which means hundreds of people are watching the show in person, with millions more watching at home. In short, it's a very bad place to decide to cheat at a game, particularly if that game involves standing on an oversized pool table in front of said audience.

Last night (Sept. 9) on 'The Tonight Show,' Britney Spears stopped by to promote her new lingerie line ... and to let Jimmy Fallon sign her up for Tinder.

See Miley Cyrus, Lea Michele, Jimmy Fallon, Demi Lovato + more celebs' audition tapes before they were famous.

Beloved teen angst fest (and starting point for such big time talents as Claire Danes and Jared Leto) 'My So-Called Life' might have been cut short -- like, way short, the series was cancelled after only 19 episodes -- but that hasn't stopped it from enduring as a modern classic that kids still relate to (and, hey, adults do, too). The series turned twenty years old just a few weeks ago, and star Danes didn't let the day go by on unmarked. Well, sort of.

Who doesn't love Meghan Trainor's 'All About That Bass?' Great song, great message and now even cooler, thanks to Jimmy Fallon and The Roots!

By now, it seems that every celebrity under the sun has taken the ALS Ice Bucket Challenge -- even your favorite Marvel stars -- but there is still a handful of big names who have yet to take the plunge. One obvious choice? Lindsay Lohan, who seems to have so far slipped through the cracks. Well, at least until one random fan challenged her to the task and then employed Jimmy Fallon to make it happen on 'The Tonight Show.' Oh, you're done for now, Lohan.

Taylor Swift finally unleashed her nerdy side on 'The Tonight Show Starring Jimmy Fallon' last night.

A choked-up Jimmy Fallon took to 'The Tonight Show' last night to pay tribute to the recently passed Robin Williams, a highly emotional affair that should help squeeze one last round of tears out of Williams' many shocked and saddened fans.

Poor Nick Cannon. Perhaps the 'Tonight Show' guest realized he'd want to hide after last night's show, thus deciding to kit himself out in a camouflage suit before he even hit the stage. Cannon was paired up with Megan Fox during the latest round of Jimmy Fallon-approved Pictionary, and the pair turned in a ... well, it was a pretty dismal performance.

Nina Dobrev just revealed a hidden talent: Beer pong champ!

Watch Helen Mirren and Jimmy Fallon play 'Mirren, Mirren'!

Here's how you know that you've got a real cultural phenomenon on your hands: when you don't even need to call it by its correct name, and everyone still knows what you're talking about. Such is the case with the E.L. James book '50 Shades of Grey,' which will soon be a movie called, well, '50 Shades of Grey.' Wait, '50 Shapes of Grape'? What did you say? It doesn't matter, you still know what we're talking about here.

During her visit to 'The Tonight Show' last night, Julia Roberts was up for a game of 'Face Balls' with Jimmy Fallon, in which the actress and host hurl beach balls at each other's faces, because of course.

The '50 Shades of Grey' trailer is alternately steamy and scary, but late-night host Jimmy Fallon wasn't content to show it to his house band, the one and only Roots, as is. Nope, that thing needed to be modified just a touch, to really make sure that the band was paying the proper attention to their trailer-watching assignment. So the 'Tonight Show' host did what anyone would do -- he inserted a scary scream face into the middle of the trailer. Obvious, right?
