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).

Will Ferrell has pulled his fair share of stunts on late night television in the past, but this latest appearance has to be one of my favorites. The former SNL star joined Jimmy Fallon on The Tonight Show dressed as Little Debbie herself. He said it's because he's the new spokesperson for the popular snack food brand.

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.

“Fifty Shades of Grey? That’s nothing!” It’s fair to assume that the last thing most people – even most late night hosts – would ask Ice T should they have him locked in a conversation is how he feels about Fifty Shades of Grey. Tonight Show host Jimmy Fallon is not most people, and when Ice T (Ice? Mr. T?) appeared on his show last night, Fallon asked him about America’s current cultural obsession. Ice T had some opinions! They’re kind of great!

Kelly Clarkson and Jimmy Fallon are pretty much the best karaoke duo EVER.

Nick Jonas has many strengths. Pictionary may not be one of them.

Last night, Taylor Swift appeared on 'The Tonight Show Starring Jimmy Fallon' then was forced to draw the host without looking and dance on a Jumbotron.

Saturday Night Live celebrated 40 years on NBC on Sunday night. One of the guests on the show was Taylor Swift. At the after party she teamed up with Paul McCartney on the bass, and Jimmy Fallon on stage to sing "Shake It Off."

The upcoming 'Fifty Shades of Grey' feature might not be everyone's cup of sexy tea, but leading lady Dakota Johnson would like to at least attempt to change the minds of potential viewers who don't think that anything—yes, anything—can be sexy with the right attitude. On last night's 'Tonight Show,' Johnson was tasked with reading off a series of decidedly unsexy lines, including stuff about Chapstick (?) and sweatpants (?) in an attempt to make them alluring.

"The Tonight Show" used to call Los Angeles home for decades. That all changed when Jimmy Fallon took over as host last February. Since it's getting so snowy here in New York, Jimmy decided to hit the road.

Thank goodness for iPad apps. On last night's 'Tonight Show,' host Jimmy Fallon -- who grows more California by the minute, as the show has temporarily relocated to the West Coast -- and guest Will Smith decided to finally give the people what they want: rapping. Well, sort of.

When we laughed earlier this week when Jimmy Fallon decided to recreate the "Fresh Prince" theme song, we thought that may be the only walk down memory lane we'd get this week. Nope! Jimmy decided to break out the cast from "Saved By The Bell" for a special flashback from Bayside Highschool.
