Fergie took the stage to perform at The Creative Coalition's Benefit Gala during the Democratic National Convention in Philadelphia on Wednesday night. The "M.I.L.F. $" singer and mom to son Axl Duhamel looked hotter than ever in a black one-piece and thigh-high boots as she sang a few of her solo hits, then linked up with her Black Eyed Peas bandmate Taboo. Fergie burst back onto the music scene earlier this month with the release of her supersexy "M.I.L.F. $" video — the clip features Fergie and her celebrity mom friends Kim Kardashian, Chrissy Teigen, and Ciara walking with strollers, breastfeeding, and taking milk showers — and obviously got people talking. "Changing the acronym to 'Moms I'd Like To Follow' is about empowering women who do it all," Fergie told Entertainment Weekly. "They have a career, a family, and still find the time to take care of themselves and feel sexy. With a wink of course."
