The 'Grenade' hitmaker sings the track from his debut album before the star-studded crowd at the Metropolitan Museum of Art in New York City.
Footage from inside 2012 MET Gala hit the web a week after the biggest night of the year in fashion was celebrated. Courtesy of Vogue, it features Bruno Mars catering the star-studded crowd gathering inside the Metropolitan Museum of Art in New York City with a live performance.
Mars got the crowd into the groove with his song "Runaway Baby" from his critically-acclaimed debut album "Doo - Wops & Hooligans". Looking sleek in a Prada suit, the Grammy-winning singer was accompanied by a live band and grabbed a megaphone at one point during the set.
This year's MET Gala was attended by the likes of Rihanna, Scarlett Johansson and Beyonce Knowles. Riri looked lovely in a Tom Ford backless crocodile dress, Johansson stunned in a Dolce & Gabbana off-shouldered gown, while Queen Bey showed off her post-baby body in a Givenchy couture gown.
