Jimmy Fallon

What makes a good Sia impression according to Celine? A little rasp and a whole lot of hair, apparently!

Jimmy Fallon is back as Sara "with no H because H's are Ew!" and Jennifer Lopez plays Gabby who finds out her dad is on Snapchat. Ew!

"I have been waiting my whole life to do this," the singer said — not of performing a song, but playing a ridiculous game with Jimmy Fallon.

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

Anna Kendrick, John Krasinski, Jimmy Fallon and more celebs face off in the new reality TV competition Lip Sync Battles, premiering April 2 on Spike.

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

Jimmy Fallon's 'Lip Flip' must be stopped. It has to end. Sure, the technology that drives this particular 'Tonight Show' segment is vaguely impressive (there are lips! and then they get flipped!), and Fallon and his various guests appear to have a good time pretending to talk out of each other's mouths, but the final execution is so terrifying, so weird, that it can only do one thing: cause nightmares.

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.

Jimmy Fallon’s supposedly good time games are becoming increasingly more complicated, threading in generally fun ideas (“let’s tell a story together!”) with weird constraints (“put you can only use three words!”) with one final, seemingly impossible demand (“and then you have to make me say this mystery word!”). Fortunately for the ‘Tonight Show’ host, he picked a game (tee hee) partner for his first crack at “Three-Word Stories.”

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?

Jennifer Garner is extremely good at Catchphrase. The 'Men, Women & Children' actress hit 'The Tonight Show' last night to chat about a variety of things -- from her new film to, oops, that one time her entire family got head lice -- but she really hit her stride when it was time to play Catchphrase with host Jimmy Fallon.

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?
