The Hawaii-born Mars also found time to finish his forthcoming debut album, tentatively titled Doo-Wops & Hooligans.
The project is "100 percent" done, the "Nothin' on You" singer told MTV News, adding that the set is influenced by his live performances.
"Every time we go into the studio we got to think about, 'OK, we're gonna perform this song.' We think, 'How are we gonna keep these people's attention?' " he explained. "So throughout the whole song, it never stops. It keeps moving. And we always flip up our show. Whenever we do our shows, you might not hear the album version. You'll get the live version."
The singer's freshman album has no release day as of press time, and he's not revealing much in terms of details.
He gave only a small hint regarding one of the guests on the project: "They have dreads.
"I got Whoopi Goldberg on my album, y'all," he said, joking.
Although the singer is enjoying his recent success, earlier this year he remarked how long his rise to the top has actually been.
"The journey wasn't short at all — it was trial and error and trial and error," he said. "It was just back and forth, man. But once 'Nothin' on You' blew up, I had these songs in my back pocket, and the label thought it'd be a good time to give people a little taste of what they're gonna get with the album. The EP came together real nice; you're gonna get a nice effect of what's in store."
