Black Eyed Peas leading lady Fergie is taking her slick and sassy fashion sense and putting it toward a good cause -- and she's telling Extra all about it.

Fergie Ferg has designed a new pair of shoes to help raise funds for breast cancer research. "If you get these in pink, they're called hope," she said. "Basically, all funds go to breast cancer research."

The pint-sized singer is known for her fun fashion ensembles and can always be seen rocking a pair of sky-high stilettos.

"There was an article one time in one of the magazines and the head title was, 'Me and My Midget,'" she said of a pic with her husband Josh Duhamel. "So I try to wear heels."
