Jimmy Fallon

Tonight Show host and comedian Jimmy Fallon is currently in the hospital while recovering from surgery today (June 26).

Ariana Grande has one set of pipes, but the "One Last Time singer shows just how well she uses them when she impersonated Celine Dion on The Tonight Show Starring Jimmy Fallon last night (March 20).

While we usually catch 'The Tonight Show with Jimmy Fallon' during the week, the comedian and late-night host filmed a special edition of the show last night (Feb. 1). To make the event even more spectacular, he enlisted some of our favorite stars including Ariana Grande, Sam Smith and Usher to take part in a cover of Queen's 'We Are the Champions.'

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.

How do you take to sexiness out of Marvin Gaye’s ‘Sexual Healing?’ Have the song covered by a barbershop quartet (plus one) starring Jimmy Fallon and Steve Carell.

Lorde talked with Jimmy Fallon about posing as Taylor Swift's manager. She also performed 'Yellow Flicker Beat.'

Daniel Radcliffe's name may be forever synonymous with 'Harry Potter,' but the British actor has already proven that his talents extend far beyond playing the boy wizard on the big screen. He can do the Broadway thing! He's got a nifty fake American accent! He can rap! Wait...what?

Just when we thought we couldn't be any more obsessed with Meghan Trainor's 'All About That Bass,' Jimmy Fallon had to come along and make it positively epic.

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.

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.

We can always count on Jimmy Fallon to tackle the hard questions. His latest challenge? Finding out exactly what Ryan Lewis does.

Last night (May 20), 'The Tonight Show Starring Jimmy Fallon' hosted a game of charades that included actors Charlize Theron and Josh Hartnett. We won't reveal who won, but we will tell you this: It. Was. Hilarious.
