Beyonce Knowles' has recorded a "f***ing insane" new track, which may be released this year.

The 'Halo' singer has reportedly finished work on a song with producer The-Dream, which another songwriter, Los Da Mystro - who is best known for working with Chris Brown - says is ready for release.

Referring to Beyonce as simply 'B', Los tweeted:"Listening to New B record Dream wrote...F***ING INSANE! Wow!! She About to Kill the game again! Had to Listen again!! Yall C in 3 weeks! (sic)"

He also tweeted to a Beyonce fan page: "All i can say i Ladies y'all got another Anthem!! Is it a BIG record (sic)."

Clarifying that he'd heard the song is due for release within a month, Los later tweeted: "That's what they sayn now... But it is the music Business. Could b sooner or lata (sic)."

Beyonce's last album, 'I Am... Sasha Fierce' was released in 2008 and has sold over six million copies to date, and earlier this week it was revealed she is picking producers and looking for new tracks for her next album, which will be her fourth solo record.

Jim Jonsin - who worked with Beyonce on tracks including 'Sweet Dreams' - said: "Beyonce, that's something, we just got a call the other day to start napping that up. We're gonna get in for a week or two so that's something I'm excited about.

"We're submitting tracks to her, see if she's digging the direction and if she does, then we're gonna follow that direction. I think she's trying to find sounds that she likes from different producers."
