Which Travie McCoy single featured Bruno Mars on its chorus?

Travie McCoy’s single “Billionaire” featured Bruno Mars on its chorus. The song was released in 2010 as the lead single from McCoy’s debut solo album, Lazarus, after his work with Gym Class Heroes.

Mars and producer-songwriter Philip Lawrence developed the melody, while Mars and Ari Levine wrote much of the song’s material during an 11-day trip to London. The hook begins with the wish to become a billionaire, and Mars’s vocal became one of the track’s defining features. McCoy initially hesitated about the song’s money-focused premise but later shaped the verses around generosity, fame, and social responsibility.

The recording is often described as a Travie McCoy song featuring Bruno Mars, rather than a Bruno Mars solo single. Mars is a featured vocalist and co-writer, while McCoy remains the lead artist. The production was credited to the Smeezingtons, Mars’s writing and production team with Lawrence and Levine.

“Billionaire” became a major international hit, reaching the top five in both the United States and the United Kingdom and earning multi-platinum certifications in several markets.
