Nicole Scherzinger and Tulisa Contostavlos battle for the X Factor style crown

Nicole Scherzinger and Tulisa Contostavlos step out onto the X Factor stage every week dressed to nines and fighting to be crowned the most fashionable judge.

And this week, both ladies put their best foot forward when it came to their style choices

Nicole Scherzinger decided to bare some skin in a strapless black leather dress that hugged her enviable figure in all the right places.

The dress by Ermanno Scervino featured ruffles in the waistline which accentuated her great shape.

Nicole Scherzinger teamed up the sexy little black dress with shoes by Giuseppe Zanotti and got into the English spirit as she pinned a poppy on her neckline.

Meanwhile, Tulisa Contostavlos stole the spotlight with a feminine dress with lilac sequins all over designed by Jovani.

The mentor of the girls category let the eye-catching dress do all the taking as she left her long brown locks wavy and kept her make-up simple with a soft pink lip color.

They were joined on stage by their fellow judges, Gary Barlow and Louis Walsh, who both looked dapper in their signature suits as they helped the ladies down the steps in their stiletto heels.

Gary Barlow stayed true to his gentlemanly style and opted for a classic suit with a white shirt, while Louis kept his ensemble all black.

Despite looking glamorous and feminine in her great dress, Tulisa Contostavlos was upset she had to say goodbye to one of the girls she was mentoring, Lucy Spraggan.

The popular contestant decided to quit the show last week, and Tulisa Contostavlos took to Twitter to express her sadness.

“I’m so sorry to lose @lspraggan from the competition,” she wrote hours before the live show commenced.

“I have had a brilliant time working with her and I hope I can continue to mentor her in the future.

“I now count her as a friend. She is an amazing girl. I love ya lucy, get well soon and my thoughts are with you. Xx”
