Bruno Mars accomplished quite a feat on Saturday evening as he served double-duty of host and music guest on Saturday Night Live. The singer/songwriter also was featured in various funny sketches, most noteably dressed up as a blonde-haired school girl. The Grammy Award-winner hit the stage twice to perform his lead single “Locked Out of Heaven,” and premiered a new cut titled “Young Wild Girls.”

Expect Bruno’s sophomore album Unorthodox Jukebox, December 11.
