Now, normally this wouldn't be a problem - imitation is the best form of flattery and all that - but in this case we smell a bit of a fashion statement...
Y'see, Tulisa is currently embroiled in a bit of a legal battle with will.i.am saying that she wrote Scream and Shout and was intended to sing Britney's part.

Yes, that does explain the weird British accent somewhat.
The song is credited to will.i.am, Jef Martens and Jean Baptiste, however Tulisa maintains that she co-wrote the lyrics.
Tulisa says she is entitled to royalities and is currently suing will.i.am for a slice of the track's £2million earnings.
So we reckon dressing up like Tulisa in the video is a bit of a salt and wounds situation.
Blonde high ponytail, trackies and piles of gold chains... we're definitely not imagining things. Well, unless Brit was chanelling Vicky Pollard.
