But Can They Sing?

Kate onstage with Babyshambles

Super-model and rock-star girlfriend Kate Moss is apparently set to retire her platforms to take up a career in music after she turns 35.

Although she's dabbled in music before, singing with ex-boyfriend Pete Doherty's Babyshambles both onstage and on their Down in Albion album, she's never done anything on her own.

A friend of Kate's tells the Sun, "She has told everyone she won't carry on modeling after she turns 35." (Kate's turning 35 in January of next year.) Says the source, "songwriting and being a singer will slowly take over."

It's hard to believe Kate can even string a sentence together, let alone write a whole song, but I'll be fascinated to see what she comes up with.

Costner Goes Back to the Old "West"

But Kate's not the only star bitten by the music bug -- Kevin Costner's set to release his own country album with his band, Modern West!

Betcha didn't even know he HAD a band -- check out their MySpace page here.

Will the Bull Durham star hit it out of the park or strike out?
