Sexy pop star Christina Aguilera has discovered the perfect method of shocking people - going out in a respectable outfit.

The controversial singer, famed for her 'barely there' clothes style, loves the reaction she now gets when she surprises people by wearing 'normal' clothes.

She laughs, "I'm a girl's girl. I like wearing short skirts one time and jeans the next. I enjoyed going to the 8 MILE premiere in a simple white shirt and sneakers.

"People were, 'Oh my God! Christina's wearing some clothes for a change!' I get a kick out of watching that kind of reaction."
