Nicole Scherzinger is back on the X Factor judging panel – and that means one thing: more amazing fashion to ogle.

The former Pussycat Dolls star has worn some show-stopping outfits in the past.

And now that she’s back, we can look forward to seeing fashion that will be anything but boring.

Here are some of her key looks from past X Factor events and shows:
