Yes, we know 'When I Grow Up' isn't even out over here yet, but the second single from the new Pussycat Dolls album has already appeared online. It's called 'Whatcha Think About That' and it's a midtempo electropop tune built around a distinctive, bhangra-ish guitar riff. Oh yes, and Missy Elliott's all over it like a rash.

The lyrics, about getting rid of your no-good-controlling-waste-of-space boyfriend, are fairly standard girly R&B fare. But there's a nice moment during Missy's rap, when she drops in a reference to everyone's favourite chart-topping lespo-pop anthem: "Up in that club it's just me and my girls, play like Katy Perry kissing on girls." Now Missy, don't you know that's how rumours start?

Truth be told, 'Whatcha Think About That' is slightly disappointing after the hyperactive pop brilliance of 'When I Grow Up'. It's decent rather than dazzling - a bit of an album track. But don't take our word for it, you can make up your own mind by having a listen over on the Pussycat Dolls' official website.
