Kate Moss has been barred by boyfriend Jamie Hince from playing her karaoke system for more than half an hour in a day, according to reports.

“Kate’s got a state-of-the-art karaoke system installed in both her London and Cotswold homes,” The Sun quoted a source as saying.

The source added: “When she’s not working she likes nothing more than getting some pals over to her place after lunch, cracking open a couple of bottles and then singing to her heart’s content.

“But Jamie is getting a little bit tired of the lengthy singalongs and he has now told her that she can only rock the mic for just half an hour a day.”

Hince, who is a guitarist in the band ‘The Kills’, had teamed up on stage with Pink Floyd legend David Gilmour at a charity event earlier this month.
