Fergie Rocks Red Sequin Minidress While Holding Baby Boy Axl

Fergie is one sexy mama.

The songstress uploaded a photo to Instagram earlier this week in which she is rocking a dangerously short, red sequined minidress and towering heels. The gorgeous new mom, 38, cradles her 5-month-old son, Axl, in the photo. She captioned it: "Mama got to hang with her lil homie today on the set of her #avonoutspoken shoot. #lilhomie."

Fergie and her husband, Josh Duhamel, haven't been shy about sharing photos of their infant on social media. In November, Fergie shared some with Ellen DeGeneres on her show and made note of how little Axl takes after his father. "[Josh has] got a little mini me," she said.
