We're almost certain Bruno Mars is sleeping like a baby today after his impressive showcase on Saturday Night Live. The R&B soul singer pulled double duty on SNL serving as host and musical guest. 

Mars recently talked with Fuse about his sophomore album Unorthodox Jukebox, buying his mom a house and his gig on SNL saying it was an "honor" to be asked to host. 

"If I go down in flames, at least I can say I did that," Mars said. 

And he shouldn't fret because he did great! The "Grenade" singer used his vocal skills throughout the show including during his monologue, and a Pandora sketch that had him emulating Justin Bieber, Katy Perry and Michael Jackson. 

Mars also performed two songs off Unorthodox Jukebox, which drops December 11, including "Locked Out of Heaven" and "Young Wild Girls." Check out the performances below.
