Who knew she could rap?!

Emma Stone made an appearance on The Tonight Show on Monday, and brought down the house with a rendition of DJ Khaled's "All I Do Is Win" as part of Jimmy Fallon's famous lip sync sessions.

The actress' skills were so impressive that the talk show host called it "the best one [lip-syncing performance] that's ever been done on the show ever."

We bet this is one of the many reasons boyfriend Andrew Garfield is smitten!
