Not that kind of trashy!

On Thursday, Fergie and a friend went to do some sexy Halloween shopping as the two went to Trashy Lingerie in Los Angeles. Oh my!

The 37-year-old Black Eyed Peas singer and her Lady Gaga look-alike friend were probably getting a leg up on the costume gathering before the big day arrives at the end of the month. I'm sure hubby Josh Duhamel will be happy with whatever she bought!
