just might be the hottest mama in Hollywood!
The "Fabulist" host recently showed off her super-slim bikini bod on the beach in Puerto Rico as she walked hand-in-hand with husband Jay Cutler.
The "Laguna Beach" alum and her football playing hubby spent some quality time together at Bahia Beach Resort & Golf Club, where they stayed in one of the club's ultraluxe, beachfront villas.
Kristin and Jay welcomed their second son, Jaxon, just 8 months ago, and the former reality star had no trouble getting back in pre-baby shape. So, how did she slim down so fast after giving birth?
"I try to work out four to five times a week and I eat incredibly healthy," she told E!'s Ken Baker. "I'm the kind of person that does not eat any toxic chemicals…I just try to eat real food. I think probably the best tip is that I try to always get a vegetable in somehow, even in the morning if you're making a smoothie, you can throw some spinach in it and it's an easy way to get a serving of greens."
Cavallari admitted she's currently "trying to put on muscle."
"I don't why or how, but after I had children, my body literally changed. And now for me, it's about trying to keep muscle on and gain muscle, so that, yeah, I don't look too thin," she explained. "It's very easy, because I have no curves, that I can look really skinny and I don't like that look. So, yes, I'm drinking protein shakes, I'm trying to put on muscle and I'm lifting very heavy weight right now."
How do you think she looks? Sound off below!
