You'll never believe what Chris Pratt did to Bruno Mars' song!

Chris Pratt is officially the Hollywood star we most want to be our wingman every weekend for the rest of our lives.

The star of the upcoming Jurassic World showed off yet new talents during a round of "nonsense karaoke" on The Tonight Show. He nailed every single made-up lyric to the Mark Ronson-Bruno Mars hit 'Uptown Funk'.

"Armpit is ice cold"? We don't know what it means, but Chris makes it work. And we're just as impressed by his hot dance moves. Check out his karaoke mastery in the video above.

Wouldn't you say it's a pretty flawless nonsense performance? Our only gripe is Jimmy Fallon. We know he secretly wishes he could be a music star instead of a lowly talk-show host, but must he always insert himself into his guests' musical routines?

At least we know for sure Jimmy won't be popping up in Jurassic World when it opens June 11. Watch the latest trailer below.
