Will.i.am has proclaimed that his next single is going to be massive.

The singer hit No.1 in the UK on Sunday (January 13) with his Britney Spears collaboration 'Scream & Shout' - and it seems the follow-up could be even bigger.

In a series of Twitter messages with Capital FM, will.i.am said that he's currently sitting on a "mega" new single. The Voice UK coach said:

"I'm so proud to have a #1 song in wonderful UK...it means so much...#proud #wowzer.""

He continued: "I think I have something mega...I felt like this before...#boomboompow to #igottafeeling...this next 1 smells big."

Will.i.am then revealed that the track would be unleashed before February, with his new album '#willpower' expected to land on February 1.
