Angela Simmons is one hot mama! It’s only been four months since the “Growing Up Hip Hop” star welcomed her first child, and she’s already flaunting her toned post-baby body in a sexy two-piece swimsuit.

The 29-year-old reality star and fashion designer took to Instagram Wednesday to post a photo of her striking a pose in a printed bikini. “First time in a swimsuit since I had my baby boy,” she wrote in the caption.

Simmons, the daughter of Run DMC’s Rev Run, welcomed a son with fiancé Sutton Tennyson on Sept. 29. The couple named their little bundle of joy Sutton Joseph Tennyson. Ever since her baby boy’s arrival, Simmons has been documenting her intense workouts on Instagram. In between sharing adorable photos of her son, she often posts videos of what she does in the gym to help her slim down and get in shape.

On Wednesday, Simmons posted a video of her jogging outside, doing donkey leg kicks and walking on the treadmill. “Had a great workout and start to my day !! Blessed !!” she wrote. In a video from earlier this week, the WEtv star was seen taking boxing lessons with celebrity trainer Coach Nelson.

Based on Simmons’ other fitness videos, it appears she’s also heavily into Pilates and squats. “What they fail to tell you is that you will never be the same after you have a baby .. you actually just become stronger,” she captioned a workout picture. “#WelcomeToTheNewMe #OnIt #GreatWorkOutThis Am @itccoachnelson @supremeteamboxing !! Thanks for building me up.”

All the working out seems to be helping Simmons reach her goal weight. Earlier this month, she told fans that she was only a few pounds away from her pre-baby body. “Coming for what I left on the table,” she captioned a photo of her post-workout. “MOOD 3 pounds more before I’m pre pregnancy weight !!! LetsGo.”
