Bruno Mars and production partner Philip Lawrence of the Smeezingtons are the pair behind [article id="1646434"]Cee-Lo's potty-mouthed breakout hit, "F--- You."[/article] The track is equal parts brutal and comical and, according to Mars, the duo's collaboration with the Gnarls Barkley/ Goodie Mob member was ideal.

Mars and Lawrence have long been influenced by Cee-Lo and the rapper/singer took to their tune like Angelina Jolie did to Brad Pitt.

"Talk about the perfect marriage, we been fans of Cee-Lo for real," Bruno Mars told MTV News. "And we became labelmates and I was just feeding that to them," he said of urging the record label to smooth the way for a collabo." 'We got to get in. I know he's working on something, we got to do something.' So he comes in the session, and it was one of the most organic sessions.

"We wrote a song and it's not for radio, obviously, with the title. We're probably gonna have to work on that. But it was a dream session come true; that was the ideal collaboration. Everyone was just putting their minds together and [we came] up with one of our favorite tracks we've ever done."

The production duo's recent credits include tracks for Mary J. Blige, B.o.B and Travie McCoy, with Mars lending his vocals to McCoy's "Billionaire" and [article id="1645004"]B.o.B's VMA-nominated smash "Nothin' On You."[/article] But the profanity-laced record was cooked up three years ago when Cee-Lo first began working on his sophomore solo effort, The Lady Killer, due December 7. The Smeezingtons delivered a rough sketch of the song that included production and a reference hook. Cee-Lo heard the music and instantly wanted the number, Mars said.

"He came in and we started singing it for him," Mars said. "And he's just, 'I love that, man. That's beautiful.' And we said, 'Let's go,' and that's all we really had -- just that concept -- and now it's blowing up."
