Pantsless Christina Aguilera Shops at Lingerie Store

Apparently what a girl needs is a pair of pants.

For the second time this week Christina Aguilera stepped out sans bottoms. On Monday night, the singer, 30, enjoyed a dinner date with beau Matt Rutler in a white T-shirt worn over fishnet stockings and not much else.

She was spotted shopping at a Los Angeles lingerie boutique (as well as upscale retailer Fred Segal) on Thursday in a similar ensemble, only this time The Voice judge accessorized with a red scarf, a trucker hat and sunglasses and sported her signature ruby pout.

Aguilera was recently on the receiving end of some less-than-flattering comments by Kelly Osbourne. On E!'s Fashoin Police, the 26-year-old slammed the singer for her weight. "She called me fat for years," Osbourne said. "I was never that fat."

Osbourne was criticizing Aguilera's performance look at Michael Jackson Tribute Concert. The mom rocked yet another pantsless ensemble with fishnet tights, heavy makeup and supersized hair.
