"Billionaire" is a song by American recording artist Travie McCoy from his debut studio album, Lazarus (2010), featuring vocals by American singer-songwriter Bruno Mars.
It was first released on March 9, 2010, in various countries via digital download as the album's lead single by Fueled by Ramen. McCoy co-wrote the song with its producers Mars, Philip Lawrence and Ari Levine of the Smeezingtons. The song was created from a melody hummed by Mars and Lawrence.
The lyrics were written during an eleven-day trip Mars and Levine made to London to work on a record, supported by Mars's label.
"Billionaire" is a reggae and pop-rap song. Critical reception towards the song was mixed, as music critics praised the song's style comparing it to the music of Sublime, Jason Mraz and Jack Johnson, but criticized its songwriting. Lyrically, the song has a money-driven hook with political elements in the verses. Such elements include helping those in need, having a show like Oprah and being on the cover of Forbes magazine once McCoy becomes a billionaire.
The single reached number one in the Netherlands, number two in Ireland and New Zealand, and also reached the top five in the United Kingdom and the United States. It was certified four-times platinum by the Recording Industry Association of America (RIAA), and two-times by the Australian Recording Industry Association (ARIA) and Music Canada (MC).
The accompanying music video for "Billionaire", directed by Mark Staubach, was filmed at various locations in Los Angeles, California. It features McCoy driving a Mini Cooper with Mars in the passenger seat. Mars and McCoy, with former Fall Out Boy Pete Wentz on the back, are shown riding different scooters.
The video is interpolated with footage of McCoy helping four people, as well a large group at the end. McCoy and Mars performed the song live on Jay Leno's The Tonight Show and Late Night with Jimmy Fallon. It was also part of Mars's Super Bowl XLVIII halftime show in 2014.
The song was re-recorded by Brazilian singer Claudia Leitte; her version outperformed the original single reaching number three on the Billboard Brazil Hot 100 Airplay chart. The television show soundtracks of Beavis and Butt-Head and American Housewife used the song.
