But who outshone the other?

Well if we were basing this week's fash off on Nicole's Asda uniform she wore during Jahmene's VT then we'd say Tulisa won hands down.

Luckily, the black and green fleece wasn't the only outfit Nicol! e donned last night.

Nope, Nicole also stepped out in an Ermanno Scervino black leather strapless dress.

The figure hugging frock, which perfectly showed off Nicole Scherzinger's rocking bod, included ruffle detailing which she teamed with a pair of black stilettos.

Seriously smoking hot.

We're not sure it would have quite a close competition if we included this outift [Rex]

Tulisa on the other hand went for a more girly look.

The singer looked incredible in a sheer long sleeved dress covered in lilac col! ored sequ! ins.

She teamed the outfit with a pair of daringly high pink heels and yet again wore her hair in loose curls over her shoulders.

Well if it aint broke.

We seriously can't decide who looked better last night so for this week, it has to be a tie.

The X Factor returns tonight when one more act will leave the competition and Tulisa and Nicole will continue to battle it out in the style stakes.
