Kourtney Kardashian almost died just to get her sexy body.

Kourt confessed that the means she used to get rid of the baby weight she put on after giving birth to Mason was so rough that she got hospitalised.

"I have the paramedics calling me telling me that Kourtney passed out, she's in the back of an ambulance," Khloe Kardashian said during Sunday night's episode of Khloe and Kourtney take Miami.

"I was just running down the beach like I always have been lately. And then I just woke up," Kourtney said, adding that she hasn't had anything to eat that day.

"She hasn't been eating a whole lot at all lately," Khloe adds.

"I've been obsessing about this weight thing a little too much," Kourtney said, admitting that what she did wasn't worth it.

"I'm so embarrassed that I punished my body for a photo shoot."
