"Grenade" is a song by American singer and songwriter Bruno Mars from his debut studio album, Doo-Wops & Hooligans (2010).
The pop and power pop song 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 lyrics carry a message of unrequited love and how Mars's heart was broken, despite his best efforts to show her his love. Elektra Records released the song as the second promotional single and as the second official single, to contemporary hit and rhythmic contemporary stations in the United States in October 2010.
"Grenade" was well received by critics, praising the vocals and emotional lyrics of the song and also considered it as one of the stand-out tracks on Doo-Wops & Hooligans.
The single reached number one in fifteen countries, giving Mars his third number one single on the Billboard Hot 100, and topping the Canadian Hot 100 for three non-consecutive weeks.
"Grenade" was certified diamond by the Recording Industry Association of America (RIAA) and seven Australian Recording Industry Association (ARIA), as well as six times by Music Canada (MC). Worldwide, it was the second best selling digital single of 2011 with 10.2 million copies.
The music video, directed by Nabil Elderkin, was released on November 19, 2010. In the video, Mars is seen dragging an upright piano through Los Angeles, by the time he arrives at the home of his beloved, he discovers she is with another man, so he decides to leave and ends up by killing himself.
Mars performed "Grenade" on the Late Show with David Letterman and during all his tours since 2010. The song has been covered by a variety of performers.
It was nominated for both Record of the Year and Song of the Year at the 54th Annual Grammy Awards.
