Jimmy Fallon

Last night, Jimmy Fallon officially ushered in a new era of 'The Tonight Show' and, besides a move to New York City, already made the show his own. Can you imagine Jay Leno ever doing The Humpty Dance in a "The Evolution of Hip-Hop Dancing"?

Jimmy Fallon closed his final episode of 'Late Night With Jimmy Fallon' last night (Feb. 7) by performing an awesome rendition of 'The Weight' with the Muppets.

First we have the 'Full House' reunion for a Super Bowl commercial, now Jimmy Fallon reunites the guys (Danny Tanner, Uncle Joey, and Uncle Jesse) from the sit-com to help ease his fears about leaving 'Late Night' for 'The Tonight Show.'

Just a few weeks' time will see the late night landscape dramatically shift, as 'Late Night' host Jimmy Fallon finally takes the 'Tonight Show' throne from Jay Leno, and 'SNL' veteran Seth Meyers joins 'Late Night' in his wake. Fallon has tapped cinema icon Will Smith and Irish rockers U2 for his inaugural 'Tonight Show' gig, but who will join Seth Meyers on the couch?

Forget about your political persuasion. This is is hilarious. Watch Bruce Springsteen and Bruce Springsteen (Jimmy Fallon) rework 'Born To Run' to address the Fort Lee, NJ bridge scandal.

Since 2003, the "Barry Gibb Talk Show" sketches on 'SNL' have popped up whenever Justin Timberlake or Jimmy Fallon have appeared on the show, with Fallon playing Bee Gees lead singer Bary Gibb and Timberlake taking on his brother, Robin Gibb. The last time we saw these characters was in 2011 and its return seemed unlikely following the death of Robin Gibb in 2012. However, the sketch mad

Few guest performers seem to get 'SNL' quite like Justin Timberlake, who has a wonderful habit of showing up on the stage and creating classic sketches and characters with seemingly no effort. In most cases, he would easily overshadow the actual guest host, but when that guest host is show alum (and current late night superstar) Jimmy Fallon, there is less overshadowing and more comedic awesomenes

On a recent 'Late Night with Jimmy Fallon,' Jimmy asked guests Joseph Gordon Levitt and Stephen Merchant to battle in an epic lip sync-off to songs like 'Single Ladies,''Super Bass,' 'Take On Me' and even 'Tiny Dancer.' Awesome!

She should have this one down! She performed it at the Macy's Thanksgiving parade and here watch Ariana Grande sing her Christmas rendition of 'Last Christmas' on 'Late Night with Jimmy Fallon!'

Classic! Watch Jimmy Fallon, Rashida Jonesand and Carrie Underwood perform a holiday medley with some of this year's most popular songs.

In case you didn't think Jimmy Fallon or the Muppets could be more adorable, check them out performing with the Roots!

Excited as we are to see 'The Hunger Games' star Josh Hutcherson volunteer as tribute this coming weekend, we had to wonder who 'SNL' would recruit for its December run. That answer has finally arrived with a resounding Paul Rudd, John Goodman, and a dual feature with 'SNL' alum Jimmy Fallon and Justin Timberlake, not to mention the musical guests!

Katy Perry chatted about everything from comedians to competition to cartoons on 'Late Night With Jimmy Fallon,' leading up to her musical performance on 'Saturday Night Live.'

Last night, 'Hello Ladies' star Stephen Merchant, Joseph Gordon-Levitt and Jimmy Fallon squared off in a lip sync contest, and things quickly got out of hand.

If you haven't yet heard, this past weekend at the annual Emmy Awards, comedienne Tina Fey had a teeny, tiny nip-slip for a fraction of a second on national television. Rather than let that get to her, though, Fey has chosen to mock the incident herself, using it as fodder for a 'Saturday Night Live' promo and in an interview on 'Late Night.'

Justin Timberlake and his favorite late-night partner-in-crime, Jimmy Fallon, are back with yet another funny video, and the results are #TotallyHilarious.
