Tulisa Contostavlos is certainly upping her game style wise, now that Nicole Scherzinger is on the scene and this afternoon the brunette beauty looked stunning when she rocked up to the X Factor’s Cardiff auditions.

The former N-Dubz singer shone in a figure hugging blue striped body con dress, which had a zip fastening at the front and displayed just enough of her amply bust to be sexy, without showing so much that the outfit became trashy.

The singer completed the look with a pair of beige peep toe heels, a sophisticated up do and a huge pair of hoop earrings, while keeping her makeup understated and natural.

The X Factor’s official Twitter page shared out these two pictures of the star just minutes ago, with the caption:

‘She’s just flown in on the red-eye from NYC. If this is what jet-lagged looks like, we’ll ‘ave some of that!’

As we previously revealed, Conotstavlos flew in from New York this morning, after enjoying a short break in American with her personal assistant.

She caught up with X Factor guest judge Rita Ora during her trip and got so drunk, that she engaged in a foul mouthed rant on Twitter and lost several thousand followers as a result.

It’s funny, because she looks like butter wouldn’t melt in these photos.
