LOL! Kate Hudson and Jimmy Fallon had a lot of fun during The Tonight Show on Monday, January 25, when they played around with the Dubsmash app on Fallon's iPad — and then shared their efforts with the audience. 

Dressed in a skintight Michael Kors Collection ensemble, including a bodysuit with a sheer panel, Hudson, 36, was already familiar with the app and eager to have a go lip-syncing to some of her favorite tunes.

But it was Fallon who had the first turn — and rather than lip-sync a chart hit, the talk show host became Oprah Winfrey!

"You get a car, you get a car, everyone will get a car!" Fallon mouthed, as he morphed into the talk show host.

Hudson squealed with laughter. "That will never happen in my show," Fallon warned his audience.

The pair then took turns to lip-sync to various celebrity audio tracks (Hudson put heart and soul into becoming Adele for a rendition of her hit song "Hello").

But it was the pair's finale duet, which Hudson informed Fallon was destined to be her kids' favorite, which got the most laughs.

Check out the funny video in the clip above.
