Jimmy Fallon and Kate Hudson take turns recording videos using the app Dubsmash on The Tonight Show Starring Jimmy Fallon.

Hollywood star + hot app = segment on The Tonight Show Starring Jimmy Fallon.

That tried-and-true late night equation got put into action once again last night (Jan. 25) when Kate Hudson joined Jimmy Fallon to play around with the Dubsmash app during her Tonight Show appearance.

In case you aren't familiar with the app, Dubsmash films you mouthing lyrics from songs or delivering quotes from movies/TV and pairs it with the actual source audio. So when it's done, you end up watching video of yourself delivering hit songs or famous quotes.

Hudson ended up 'singing' Adele's smash "Hello," the Ricola ad and Baha Men's immortal "Who Let the Dogs Out," among other things.
