Jimmy Fallon

It's been a big week in the world of 'The Avengers'. There was the official trailer, the extended trailer, our set visit report, a bootleg clip and even the trailer for the third 'Avengers' movie, 'Avengers: Infinity War'. But, even with all those things, nothing can top the 'Avengers 2' trailer as voiced by Pee-wee Herman.

Jimmy Fallon may be a professional performer, but even the highly musical 'Tonight Show' host is no match for professional musician skills of 'The Voice' hosts Gwen Stefani and Blake Shelton. The 'Tonight Show' host invited the pair on to the show last night for an epic lip sync battle, and things got ugly -- and quickly.

This is the natural progression of 'Tonight Show' host Jimmy Fallon's assorted warblings and big-time musical impressions: a full-scale musical medley co-starring Barbra Streisand. The songstress has a new album out -- her 34th! -- that's titled 'Partners' and features just a mess of duets between Babs and a bunch of male partners. Get it? Partners?

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.

Jimmy Fallon has never been a teenage girl. Taylor Swift, however, has. Still, the veracity that Fallon brings to his performance as a teen in his fake-talk-show-within-a-talk-show, 'Ew!,' is pretty striking -- he somehow seems like more of a teenage girl than his guest, who was a teenage girl mere years ago. It's madness!

'The Tonight Show' is down in Orlando, Florida, this week, camped out at the Universal Studios backlot for some road-tripping fun, and all the better to serve up some exciting sneak peeks at the theme park's newly expanded Wizarding World of Harry Potter. Jimmy Fallon decided to really get into the spirit of things, dragging his faithful announcer Steve Higgins over to Diagon Alley to pick out some shiny new wizarding wands from master wand shop Ollivanders.

Well, this one pretty much sells itself. Jimmy Fallon unveiled a Father's Day-targeted take on his ever-popular "Evolution of Dance" on last night's 'Tonight Show,' and this one just hit it right out of the park.

"I'm no Adele Dazeem," joked 'The Amazing Spider-Man 2' star Andrew Garfield as Jimmy Fallon handed him a guitar on 'The Tonight Show.' At this point, celebs should know that if they don't want to showcase their hidden talents on late-night TV, they shouldn't bring them up around eccentric hosts. While Garfield seemed a little hesitant to "let it go," as they say, given that th

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?

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.
