Bruno Mars dropped in on “The Ellen DeGeneres Show” for his third visit today. The pop singer delivered bare renditions of his hits “Grenade” and “Just the Way You Are,” fronting a string quartet and two backup singers while looking dapper in the spotlight, rocking a jean jacket, shades, and his signature fedora.

“Me and B.o.B, we performed ‘Nothin’ on You.’ This was like [our first] live performance on TV. So thank you for supporting my career,” a grateful Bruno told Ellen, who embarrassed the star by showing a clip of him impersonating Elvis as a child in the 1992 film Honeymoon in Vegas.

Watch Bruno’s first performance on the show since October before he went on to earn seven Grammy nominations.
