Pixie Lott has got a lot to learn about diva behaviour

Sooner or later, someone's going to have to take Pixie Lott aside and tell her to start acting more like a popstar.

All smiles: Pixie Lott in Camden last night

The 18-year-old Mama Do singer still lives with her parents in Essex — instead of having a riotous bachelorette pad in Camden, or a permanent booking at The May Fair hotel.

And last night, when she felt a bit peckish while out and about in Camden, Pixie decided to drop into Nando's fast food chain.

Waiting patiently: Pixie in Nando's

Hasn't anyone told her that she should be off to The Ivy, Nobu or any of the other restaurants where celebs go to be seen?

Pixie seemed relaxed and happy as she sat waiting to be served her food (once again, that's not very diva-like) and later was all smiles as she got back into her waiting car. She was then driven to the Hilton at Stansted, where she continued to party with friends in the hotel's bar. It seemed like a long way to go just for a drink with chums, but Pixie is flying out from Stansted today for a gig in Berlin.

Unmistakable: Pixie makes her way into the fast food chain

We just hope she remembered to ask her Nando's waitress for a restaurant loyalty card... she'll soon be entitled to a free quarter chicken!
