According to reports Will.i.am is sick of working with one contestant on The Voice UK who has become something of a diva.

Cleo Higgins, who had a taste of fame back in the 90s with her group Cleopatra has a bad attitude behind the scenes and with other contestants according to The Mirror.

An insider at the show told the newspaper that Cleo is “the worst diva we've had” after several incidents back stage.

She apparently has been showing little interest in any advice that Will.i.am tries to give her despite the fact that he has had a very successful career with a string of awards to back it up.

“At one rehearsal she started screaming and shouting at Will to put his mobile down and concentrate on her,” the insider also revealed.

Despite reports of her conduct, a spokesperson for Higgins claims that her relationship with Will.i.am is good and there is no feuding between the two.

Will.i.am has previously got into trouble after using his mobile whilst he was carrying the Olympic torch so he has been known to use it at inappropriate times.
