Pop star Pixie Lott competed with Miley Cyrus in the controversy stakes during a party for the American singer in London by flashing her nipples in a tiny mesh top.

The Wrecking Ball hitmaker threw a party at top nightspot Madame JoJo's in Soho and invited a number of celebrity guests, including Kate Moss and Skunk Anansie singer Skin.

Lott was among the revellers and arrived with her model boyfriend Oliver Cheshire, but she left onlookers stunned as she showed off her bare breasts through a revealing sheer crop top.

Obviously trying to compete with Cyrus' outlandish style, Lott added a pair of kooky yellow sunglasses to her ensemble.

However, Cyrus refused to be outdone, and left the venue in the early hours of Friday morning (09May14) wearing just a bra and low-slung jeans.
