Kate Hudson and Jimmy Fallon had a roaring good time Monday night on "The Tonight Show" using the popular Dubsmash app. The actress and host of "The Tonight Show" used Fallon's iPad to play the app and then shared the hilarious results with the audience.

Dubsmash is an app that allows the user to pick from an endless amount of audio clips and then lip sync over the clip. As the person moves their mouth with the audio, the app records the person's facial expressions and plays it back.

Fallon was up first and took on Oprah Winfrey's famous "You get a car! You get a Car! Everybody gets a car!" followed by a Woody Woodpecker impersonation. The actress was up next and performed a melodramatic Dubsmash of Adele's "Hello" and the Ricola cough drops theme song. The final Dubsmash of the night was a duel effort between the two as they both took on the Baha Men's 2000 classic one-hit wonder "Who Let the Dogs Out."
