Kourtney Kardashian is one hot mama!
The "Keeping Up With the Kardashians" star debuted her post-baby bikini bod in Mexico on Wednesday, showing off her killer curves just four months after welcoming son Reign.
The mother-of-three was spotted soaking up the sun in a black bikini top and black high-waisted bottoms while on vacation in Punta Mita at Casa Aramara with her kids and Scott Disick.
In a new interview with Harper's Bazaar, the brunette beauty opened up about getting back in shape after baby.
"I like to take my time and not try to put too much pressure on myself, but it's hard," she told the mag. "I think I forget every time — you give birth and you want your stomach to be flat again. It does take a lot of work, but I usually start slowly by going on walks with the baby…but now I'm in full force."
The oldest Kardashian sister credits a trainer for helping her stay motivated at the gym. "Having somebody else to work out with really helps motivate me," she added. "I also try to eat really clean and at home as much as I can."
Lookin' good, Kourt!
