Lady Gaga set to sex up X Factor

London (ANI): Pop singer Lady Gaga, who's known for her bizarre style, is keeping X Factor boss Simon Cowell guessing about what exactly she'll wear while performing on the show next week. The 23-year-old singer is famous for wild outfits that have seen her shooting sparks out of her bra, and wearing only gaffer tape over her nipples.

And producers are said to be confused over what she'll wear in the show. "Getting GaGa is a big coup for the show, but she is so unpredictable that bosses are desperate to find out what she'll be wearing before the big day," the Daily Star quoted a show source as saying.

The American singer has recently spoken about her love for 'the male sexuality'. The 'Poker Face' hitmaker, who is openly bisexual, insisted that she is able to separate love from sex. "In love there are no rules or boundaries. But I separate love and sex. I just love the male sexuality. Men have something that I miss but that I really appreciate," she said.
