NOW, Britney’s had her problems in recent years so what she could really do with is a few hits to remind us what she’s all about. And, to be fair, that’s pretty much what she’s done – the title track and current single Womanizer stand up and, erm, shake it all about.

For all her woes, Britney has never been far from the headlines and, however poor she was on X Factor recently, we all know who she is.

Following the minxy machinations of Blackout, Circus returns to what she does best – frothy, gimmicky, sexually playful candy pop.

If You Seek Amy (go on, say it quickly), the frantic Mmm Papi and the bubblegum of Kill the Lights showcase manic Britney, while ballads like Out From Under offer a glimpse of what she could be.
