Reality personality Kourtney Kardashian has revealed her regret over a rash decision to undergo breast augmentation surgery when she was 22.

“It was so dumb,” Kourtney, now 30, says of procedure to enlarge B-cup boobies to fully-loaded Cs.

“It was kind of an impulse,” she explains. “I just got the idea in my head one day, and that was that. There was no talking me out of it. It was so dumb.”
