Britney Spears has debuted a commercial for her new fragrance.

The singer and X Factor USA judge is releasing Fantasy Twist onto the celebrity scent market - an industry which also includes stars such as Justin Bieber and Lady Gaga.

Perfume is nothing new for Spears, however, with the pop star now on her eleventh variety of perfume.

Fantasy Twist's selling point meanwhile is its "two fragrances in one".

The advert for the perfume sees Spears walk down a hotel lobby in a number of different outfits as curious onlookers peer through their doors.
