British singer Pixie Lott is adamant she did not strip naked for a new pop promo, insisting she wears a barely-there bodysuit in the clip.

The Mama Do hitmaker released Nasty, the first single from her new, self-titled third album, on Monday (10Mar14) and the video for the track features a scene of an apparently nude Lott with just a purse preserving her modesty.

However, the singer has now spoken out to assure fans she did not disrobe for the promo and was covered with skin-coloured fabric.

Lott tells U.K. daytime show Loose Women, "You know I'm not (naked). It's an illusion. Potentially it could be but I am not actually, I've got a little bodysuit going on."
