LONDON: Supermodel Kate Moss made it ladies night at the launch of Beth Ditto's new fashion line on Wednesday, when she jumped onstage for a round of karaoke with the larger-than-life singer.

The catwalk queen was supporting the London launch of her rocker pal's new style range for British high street store Evans when the pair decided to treat the appreciative audience to a sing-a-long.

Guests including Kelly Osbourne and Simon Cowell cheered them on as they danced around on the stage together.

It's the second time in recent weeks that Moss has shown off her vocal talents with an all-star duet - she sang with Pink Floyd legend Dave Gilmour at a charity bash last month.
