Splash NewsJust two weeks before Kristin Cavallari revealed to E! News that she's "trying to put on muscle" so she doesn't look "too thin," the hot mama proudly flaunted her bikini bod on the beach in Mexico with her hubby.
And yes, Jay Cutler is one lucky man.
The 28-year-old blond beauty was spotted in Puerto Rico, where the erstwhile Hills star showed off her insane figure in a tiny black two-piece while strolling in the sand hand-in-hand with her man, who was dressed casually in a pair of white swim trunks and a blue V-neck T-shirt.
Seemingly putting us all to shame, the mother of two put her hot bod on display, proving her dedication to fitness regime (she tries to work out four to five times a week) is clearly paying off.
According to an eyewitness, the fashion designer and the NFL quarterback looked "very relaxed" as they walked around the shoreline and appeared to be "immensely" enjoying their quiet getaway.
"The two were always holding hands and smiling at one another," the insider tells us. "They both looked as if they only had eyes for each other."
The parents of two boys (under the age of three!) stayed at the Bahia Beach Resort and Golf Club, where the couple "spent a lot of time walking on the beach and just relaxing."
"It appeared to be great rest for the both of them," the source adds. "They look like a loving couple, who really enjoyed time alone."
Earlier this week, Cavallari made headlines when she opened up about her super-strict diet and fitness regime, admitting she works her butt off in the gym and she eats "incredibly healthy."
"I'm the kind of person that does not eat any toxic chemicals…" she said. "I just try to eat real food."
She also admitted she's currently trying to bulk up her pin-thin frame while confessing (much to the envy of many women) that it's easy for her to look too thin.
"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."
