Motherhood has changed Fergie from head to toe.

"Now I'm getting more into the flats section because I have a kid," the new mom to baby Axl Jack told ABC News Radio, with a laugh. "So pregnancy and becoming a mom have really lowered my heels!"

While her group, The Black Eyed Peas, is on hiatus, the 38-year-old singer continues to run her mini-empire that includes shoes, wine, makeup, nail polish, fragrance and other products from home so that she can be there for her 3-month-old son with husband Josh Duhamel.

"I've been so blessed to be able to work from home," she gushed. "I mean, I can't tell you how many times I'm sitting there in a meeting or a conference call or doing approvals online, and I don't have to get dressed. … I can feed my son. It's wonderful!"

While Fergie has the luxury of working from home, she knows plenty of women don't. She's teaming with the charity Dress for Success, which provides disadvantaged women with appropriate clothing for job interviews and the workplace, to create "Giving Shoe-Day" as part of the second annual Giving Tuesday, or national day of charity.

The singer is asking women to donate their unwanted professional shoes to one of more than 50 locations in the U.S. The top 10 shoe donors across the country will receive a very special gift: a pair of limited-edition shoes designed by Fergie for her company, Fergie Footwear.

"I've always wanted to do this," Fergie told ABC News Radio. "I've had this dream of creating this limited-edition shoe, and we made it happen finally this year, and 40 percent of the profits are going for Dress for Success, with a minimum of us donating $40,000."

The limited-edition shoe is called the Palace Heel; it's fire-engine red and super-sexy.

"I'm all about empowering women, helping them to become financially independent, and it's really just a great cause for the holidays. I really took to it, and it's perfect," Fergie said.

The singer even plans to give away many of her own shoes, of which, she said, she had "a lot."

As for her singing career, Fergie told ABC News Radio that she is planning a follow-up to her debut solo album, "The Dutchess," which would likely be released before a new Black Eyed Peas album.
