It looks like there might be further tension brewing between Kate Moss and Sienna Miller - Kate has previously accused Sienna of stealing her friend Rhys Ifans and her fashion style, now it looks like Sienna might be chasing after Kate’s big dream too: dueting with a rock star boyfriend.

A source explained that Rhys, the one-time lead vocalist of The Super Furry Animals, is always strumming a guitar and making up songs - and after deciding to record some of his material at a studio, has invited Sienna to join him.

The source told the Daily Express: “Rhys really likes Oasis, particularly Noel Gallagher, so that’s the kind of music he’d like to make.”

“Sienna also enjoys singing and has dreamed of one day being a rock star. Rhys has been encouraging her to do something about it.”
