Bruno Mars, Philip Lawrence, Ari Levine, Brody Brown, Claude Kelly, Andrew Wyatt
"Grenade" is a song by American singer and songwriter Bruno Mars from his debut studio album, Doo-Wops & Hooligans (2010). A pop and R&B ballad, "Grenade" was written and produced by The Smeezingtons (Mars, Phillip Lawrence, Ari Levine) with additional songwriting by Brody Brown, Claude Kelly, and Andrew Wyatt. The song was developed from an unreleased track with similar lyrical themes played by record producer Benny Blanco to Mars. "Grenade" was completely rearranged and re‑recorded two days before the album's release. The song's lyrics carry a message of unrequited love and how Mars' heart was broken, despite his best efforts to show her his love. Initially released as a promotional single on September 28, 2010, it was later announced as the album's second single, released by Atlantic and Elektra Records.
