The expecting star showed off her growing baby bump on Monday night at the Los Angeles premiere of husband Evan Ross' new movie, "Just Before I Go."
Sporting a floor-length teal silk gown with a black overcoat, the blonde beauty was glowing as she flaunted her blossoming belly. She paired the chic ensemble with a braided bohemian 'do and smokey eye makeup.
The 30-year-old actress, who announced she's expecting a baby girl, has been focusing of her fitness as she approaches her due date.
In fact, she takes two to three Cardio Barre ballet classes per week!
"She wants to stay fit and strong and maintain a healthy weight. Also to feel good," Richard Giorla, the founder of Cardio Barre told E! News. "The weight and energy makes it more challenging, but she never complains and always gives her best."
While Ashlee and Evan are anxious to meet their little one, it seems the actress' six-year-old son, Bronx, is even more thrilled to have another sibling.
"He wanted to have a sister, so he's really excited! He's got a little brother. Now he's going to have a little sister!" Simpson told Us Weekly in February.
Bronx is already big brother to Saint Laszlo, Pete Wentz's son with girlfriend Meagan Camper.
We can't wait to see the couple's new addition when she gets here!
