Black Eyed Peas star Fergie has joked she wants to sleep with Cheryl Cole.

The 'Boom Boom Pow' singer - who is married to actor Josh Duhamel but has previously admitted she is bisexual - has joined in taunting her bandmate will.i.am about how close he's been getting to the 'Parachute' singer while the two acts tour Europe together.

A source told The Sun newspaper: 'Fergie has been telling everyone she's more likely to sleep with Cheryl before will does.

'Everyone has been teasing him about his crush. But when Fergie came out with this, everyone fell about laughing.

"She's mentioned it a few times now. And even Cheryl thinks it's hilarious

will.i.am, 35, worked closely with Cheryl, 26, on her debut solo album '3 Words' which he co-produced and wrote a number of tracks on.

The other Black Eyed Peas members - Taboo and apl.de.ap - have also been taunting the pair about the amount of time they've been spending together in will.i.am's mobile studio while on the road.

will.i.am has been very vocal about his support for Cheryl in the wake of her split from cheating husband Ashley Cole, and has pledged to always be there for her.

He said: 'I just still can't believe Cheryl was ever cheated on. I mean, what has to be going through your head to cheat on Cheryl?

'If she's in New York, I'll get on a flight to see her, if she's in Los Angeles, I'll get on a flight to see her - I'll even come to London. If she needs me she knows I'm there, no excuses.'

Black Eyed Peas, supported by Cheryl, are currently in the UK and play London's O2 Arena tonight (06.05.10), and Birmingham's LG Arena on Saturday (08.05.10).
