Bruno Mars has recently premiered the music video for "Grenade", the official second single from his debut album "Doo-Wops & Hooligans". The midtempo ballad was produced by The Smeezingtons and has peaked thus far at #30 on the Hot 100. The music video was filmed in Los Angeles and was directed by Nabil (Kanye West, Estelle). LOL all that hard work with the piano to get that ending? xD. Check it out.
