Britney SpearsBritney SpearsBritney Spears is back doing what she does best.

No, not shaving her head or swimming in her knickers.

Instead, Brit is bringing her booty boogie back.

We just love a comeback kid, and it looks like Britney is it.

The Toxic star has been snapped hard at work on her latest project, the music vid for a new tune.

Brit was busting some moves at a warehouse in LA, no doubt practising for the song, which is rumoured to be titled Get Back.

Rather apt, we reckon.

Is Brit implying she's getting back at someone or something?

Or, maybe it's just a tune about asking people to get back, as in stand back?

Perhaps she's celebrating getting her music career back?

Whatever the case, Trousersnake can keep his Sexyback. Big up to Brit being back in the biz.
