This reality star is feeling some major regret.

Rich Kids of Beverly Hills star Morgan Stewart dished to fans about her plastic surgery choices and remorse, and she wasn't holding back.

"Ummmmmm why I ever thought putting s–t in my lips was a good idea is insane," she wrote. "My right upper lip STILL has a ball in it …and she injected the s–t out of it with no numbing cream, OK? There were tears."

The 28-year-old newlywed — who married costar Brendan Fitzpatrick in May — revealed that she believed she had "uneven" lips before she underwent the procedure, but has since had a change of heart.

"I'm realizing the less you f–k with yourself the better," she added.

Lesson learned!
