Cee-Lo Green Says 'F*ck You' Success Was 'Pleasant Surprise'

Cee-Lo Green has called the success of his new single 'F*ck You' a “pleasant surprise”.

The Gnarls Barkley star released the track, a semi-fictional attack on a former girlfriend, online last week.

The video has gone on to become a huge hit on YouTube and even inspired a spoof version from rapper 50 Cent.

“I think it's totally surpassed just about everyone's expectations,” Gren told Entertainment Weekly. “We had a clue — I mean, it's a very noticeable song — but this has been extraordinary."

The song, released on has been re-branded 'Forget You' so it can be played on the radio in the UK, is released next month.
