We just can't seem to get the image of Fergie performing on "Good Morning America" out of our heads.

First, we are utterly obsessed with her graphic blue minidress by Indian label Falguni & Shane Peacock, which now solidifies the up-and-coming brand that shows at London Fashion Week. (It's rumored that Lady Gaga will soon sport one of their futuristic designs.)

To complete her vampy look, The Black Eyed Peas frontwoman paired the sexy thigh-baring number with a pair of black "Jigsawed" heels from her Fall 2010 Fergie Shoes collection.

"The 'Jigsawed' is one of my favorites," Fergie tells StyleList of the $79 strappy sandal that features crocodile-embossed leather and also come in chestnut brown and turquoise; available at FergieShoes.com.

Adding, "It has ankle support and a sturdy heel which makes it easy to dance and move around on stage."

And that she did, performing a series of BEP's hits while running the length of the stage and shaking her famed lady lumps.

So just how much of Fergie herself goes into the shoe designs?

"When working with the Fergie footwear designers, I talk to them about my many inspirations: styles, designers, traveling, and colors," she says.

"I like to combine different cultural ideas. My collections Fergie and Fergalicious by Fergie are fun, edgy, and are all pieces I wear, whether I'm on stage, running errands or out dancing. I'm just a shoe fan! I can never get rid of my old shoes even if they go out of season."

The rest of Fergie's Fall 2010 footwear collection includes plenty of boots, including sexy over-the-knee styles and peep-toe booties, as well as shoes that play with rich texture and shiny hardware.

To go with the nude trend of late, the palette is mostly neutrals, with pops of violet, wine, and sapphire hues. For Spring 2011, the powers that be at Fergie Shoes tell us to expect the songstress to explore the rampant military trend seen on many a runway.

This isn't the first time Fergie has gone super-futuristic in a getup by Falguni & Shane Peacock. Check out her bold bodysuit by the designers.
