It’s no secret that the Kardashians have some of the best bodies in the world. The oldest Kar-Jenner sis, Kourtney Kardashian, is about to turn 40 on April 18, and believe it or not, the milestone birthday has her rethinking her super strict dieting approach and embracing her body in a way she hasn’t before.

“For the past couple of years, Kourtney has been totally obsessed with being as thin and toned as possible,” an insider told Life & Style about the 39-year-old’s infamous lifestyle choices. “She’d never miss a workout or cheat on her diet and was super strict about avoiding dairy, gluten and sugar.”

Any fan of Keeping Up with the Kardashians could tell you that Kourt takes her fitness and wellness regimens super seriously — but clearly, that’s why her bod looks as fierce as it does. But it seems like the POOSH boss is getting a little more casual about her schedule.

“Recently, she’s really loosened up. She’s treating herself to dessert all the time and thinks nothing of knocking back the drinks on a night out and then loading up on carbs the next day,” the source continued. That definitely doesn’t sound like typical Kourt but we think this could be a good thing. Besides, everything in moderation, y’all.

The new move is all thanks to the monumental celebration just around the corner. “Kourtney says it’s all down to turning 40 and that she’s never felt more confident,” the insider explained. “She isn’t about to let herself go completely but she’s a lot more relaxed and is embracing her body like never before!”

The Kar-Jenners are known for flaunting their incredible ~assets~ but Kourt has been radiating serious confidence ahead of her big birthday and we totally don’t blame her. On April 11, she posted a super sexy photo of herself enjoying a hot tub in the middle of a snowy tundra with a gold bikini on. Yeah, we drooled. Keep the confidence coming, Kourt — 40 is gonna look good on you.
