Hilary Duff is certainly one hot mama!

The 24-year-old mommy of baby Luca flaunted her after-baby, bikini body while in Mexico on a vacation with her loved ones. Duff, who is married to Mike Comrie, gave birth to Luca Cruz Comrie on March 20. The couple joined Duff’s sister, Haylie, and their mother, Susan, for a much-needed getaway this week.

The former Disney teen star was spotted holding a sleeping Luca in her arms while wearing a black bikini that showed off her slim figure. The three-month-old baby was protected from the sun in a swim shirt, trunks, and a cute little orange hat. On June 1, Hilary told Us Weekly that she has decided to lose her pregnancy weight, but in a healthy way.

“I think if you ask any pregnant mom, they’re like, ‘I want my body back,’ but it takes time. It takes nine months for your body to get that way, and it’s putting on that weight on purpose. Obviously, I’m not where I want to be eventually, but I’m working hard, and I’m doing everything I can to lose the weight the right way. The second I start to get down like ‘what happened to my body,’ I look at my beautiful baby, and I’ve never been more appreciative for this body that I have.”
