Whoa! Who knew that Leonardo DiCaprio could spit some serious rhymes?

The prolific actor showed off a whole other side of his talent while partying at 1OAK nightclub in Los Angeles on Thursday, Sept. 18, rapping the song 'Scenario' with Jamie Foxx -- and DJ D. Painter got the whole thing on video (which you can check out above).

"Leo DiCaprio rapping 'Scenario' with Jamie Foxx!!! Epic to say the least," Painter captioned the Instagram vid. "@1OakLA was insane last night! He's wearing a hat and has a huge beard but trust me, it's Leo."

And trust us, he can really rap, flawlessly spittin' rhyme after rhyme without slowing down or even pausing to take a breath. Pretty impressive! And it looked like the crowd agreed, dancing and turning around to stare in awe at the star and his serious rap game.

DiCaprio and Foxx were at 1OAK celebrating club promoter Richie Akiva's birthday, E! News reports. Jason Derulo, Diddy and Robin Thicke all hit up the bash as well -- but no one quite did it like Leo.
