Christina Aguilera's fashion allergy

Christina Aguilera loves wearing latex even though it gives her an itchy rash.

The singer - whose new single 'Not Myself Tonight' shows the pop star in a number of racy and provocative outfits - admitted shooting the video for the raunchy song was "torture" because of the tight latex clothing.

She said: "For my video shoot I didn't go to bed until five in the morning... in the freezing rain, in the cold, wearing a two-piece red latex outfit. Torture! I got nauseous with exhaustion from the video shoot. It was just a long day. Did I get a skin allergy from the latex? I did get a little bit of a rash at one point. Where? Next question!"

The 29-year-old beauty - who has a two-year-old son, Max, with her music producer husband Jordan Bratman - admitted her spouse loves to see her in fetish clothing, although she wouldn't like it if he tried to match.

She said: "It's beautiful...I'm really into fetish gear and latex is really making a strong statement for me. Good body contours. Has my husband worn it? I would not know! And I'll never know! You don't want to get your b**ls caught in that."

The only time Christina hasn't worn such provocative outfits is when she was pregnant.

She added to Q magazine: "Have I ever toned it down? Never! Well, maybe when I was pregnant. There was no latex then."
