Tulisa turns heads with bob-style hairstyle... as Nicole Scherzinger looks more than all white in trouser suit

Tulisa Contostavlos and Nicole Scherzinger's style choices have been a hot topic of conversation amongst X Factor fans.

But on Saturday night, the former N-Dubz singer, 24, threw something different into the mix with her bob-style haircut.

However, it appeared the North Londoner hadn't gone for the chop - she had simply tucked her long hair out of sight, give the impression of having a shorter do.

Tulisa's short 'do perfectly complemented her 1920s-esque shimmering Temperley London floor-length gown.

She teamed the show-stopping gown with a pair of black Kurt Geiger heels and Folli Follie earrings.

Meanwhile, American singer Nicole, 34, was going for a more androgynous look in white Jean-Pierre Braganza suit.

The women's very different style choices came after Tulisa appeared to be catching up with Nicole when it came to her X Factor outfits on last weekend's shows.

Recently, fellow judge Louis Walsh claimed Nicole was winning the fashion wars and urged Tulisa to 'up her game'.

He said: 'I think Nicole gets it right nearly all the time. Tulisa has had to up her game.

'Nicole and Tulisa have about six people each tending to their beauty and styling needs. I think Tulisa is probably turning into J.Lo.'
