On Friday night the singer returned to her hotel following her gig at the O2 dressed a bit like one of The Incredibles, just with a very slight difference; she had a little camera concealed in her shoulder. Pretty standard then.

After that ensemble, Lady GaGa then headed out on Saturday night wearing a see-through dress paired with a diamante encrusted lobster head-piece. Words fail us.

Meanwhile sources backstage at GaGa’s 02 concert claim that the singer was acting like a complete diva before going on stage.

Apparently the Just Dance songstress started to throw a strop after she realised everything wasn’t “perfect”. A source said:

"She was clearly not in the mood to be messed with and wanted perfection but didn't feel she had it. She went totally crazy backstage and started screaming at her costume director when something didn't look right. Despite being told she had to go out to smoke, she grabbed a cigarette and lit up - proceeding to chain-smoke for the next half an hour despite being told by numerous staff that it wasn't allowed.”

Flouting the smoking ban, tut-tut GaGa you naughty thing. Anyway, GaGa’s tantrum didn’t stop there; she then continued to have a hissy fit about food. The source added:

"Then when she went to eat, she went bananas when she saw cartons and cans in the canteen. She demanded glasses saying she "wouldn't drink out of that sh*t" and shouted at canteen staff who put that 'sh*t' out there. She wanted fried chicken which had been laid on especially for her but she spat it out rudely after one bite and said it tasted "wrong". Then she made three of her entourage go out and find fried chicken that would be "more American".

What the Lady wants, the Lady gets…
