Kate Hudson and Fergie are in fine spirits while on a girlie night out in Greenwich Village, New York.

The unlikely new BFFs became pals after working together on upcoming movie musical Nine.

Kate plays a Vogue journalist in the flick, while the Black Eyed Peas singer has a less glamourous role as a prostitute.

We hope Fergie didn't overdo it on the beverage front - the recovered crystal meth addict recently revealed that she's rather partial to wine but makes sure she sees a therapist the day after a big night out.

The pair also have something else in common, having recently dyed their blonde locks brunette.

Better blonde or brunette?
