Leggy lady: Britney's mini dress clung to her curves and showed off her slim pins

Britney chose a bright pink mini dress that clung to her every curve and boasted a sheer panel down the chest.

The short frock showed off Britney’s slim legs and she topped her colourful dress with a pair of black platform pumps.

Britney’s ash blonde hair looked freshly dyed and it was styled into tumbling waves for the occasion.

She'd also had fake talons put on after she was spotted with bloody and bitten nails at the Fox UpFront Presentation in New York on May 14.

Not to be upstaged: Britney tweeted that the rest of the panel were all waiting on Simon Cowell

Nailed it: Britney had clearly had a manicure after displaying bitten nails at an X Factor presentation on May 14

It seems that the Till The World Ends singer won’t be letting fellow judge Simon Cowell upstage her as a diva.

Britney posted on Twitter upon her arrival at the studios: ‘Just arrived for @TheXFactorUSA auditions - hope everyone is ready! Still waiting on @SimonCowell of course....’

Meanwhile Simon tweeted what appeared to be a joke response to the singer.

'I have been waiting for @britneyspears for two hours. Still can't find her. @TheXFactorUSA' he wrote, then later adding: 'Into the lion's den!'

While Britney chose a show-stopping approach to her outfit for the first day of filming for the show, the other new addition to the judging panel opted for something simpler.

Sweet and summery: Demi Lovato chose a more simple approach in a patterned sundress, leather jacket and ballerina bun

Demi Lovato donned a lime green sundress with a black pattern swirled across it, and dressed the summery frock down with a chunky leather jacket.

The 19-year-old added an elegant touch to her look with a ballerina bun and a pair of black peep toe heels.

Meanwhile L.A. Reid looked dapper in a charcoal suit and cobalt blue tie, and Simon was sporting a white T-shirt and stonewashed jeans when he eventually showed up.

Once inside, the women reportedly got into their stride quickly and within the first five minutes Demi had dubbed Simon 'Grandpa'.

The megastar then got his revenge by telling the crowd, 'Demi is single you know,' although the move later backfired when L.A. hit back: 'Simon's single too!'

Once the auditions were underway, Britney started a worldwide Twitter trend by sending home a hopeful with the words 'I pass'.

Meanwhile, Lovato said that she was having a ball.

'OMG!!! This is so much fun! #XfactorUSA,' she tweeted.

And it appears that the Disney star also seems to already having some banter with L.A Reid.

Happy chap: Simon Cowell seemed in great spirits as he got ready to see how his new judging panel would fare

Diva behaviour: Britney wrote on Twitter that Simon had shown up late for the gang's first day of filming

'Day 1 @TheXFactorUSA and I have already been cut to shreds by @ddlovato. Let the games begin!' Reid wrote on his Twitter page.

A new promo for the upcoming second season of the show has just been released, and it seems Simon may have underestimated what he was in for when he hired the fiery singers for the panel.

Simon can be seen sitting in a chair, presumably for an interview, and asks: ‘What was I thinking?' before bursting into a fit of laughter.
