Mars had an unsuccessful stint with Motown Records, but then signed with Atlantic in 2009. He became recognized as a solo artist after lending his vocals to the songs "Nothin' on You" by B.o.B, and "Billionaire" by Travie McCoy, which were international successes, and for which he co-wrote the hooks. His debut studio album, Doo-Wops & Hooligans (2010), was anchored by the U.S. Billboard Hot 100 chart-topping singles "Just the Way You Are" and "Grenade", as well as the number-five single "The Lazy Song". His second album, Unorthodox Jukebox, released in 2012, peaked at number one in the United States.
