Hell hath no fury...
In this scene from Thursday's all-new episode of Revenge Body With Khloe Kardashian, Gabriela Cardenas is determined to get back at her ex-fiancé and baby daddy after his wandering eye forced her to call off their wedding.
"I found out that he had been cheating," she tells Khloe Kardashian. "I have this wedding dress that I bought, and I actually bought it the day before I found out about the girl. I went shopping with my bridesmaids on Sunday, and then on Monday I found out. It was devastating, for sure. I called off the wedding that same day."
Gabriela then explains how the breakup took its toll on her emotionally.
"In this whole chaos of calling off my wedding, I've put on 30 pounds in the last five, six months," she reveals. "So, it's a lot of weight really fast, and because I didn't want to make him look like a bad guy to my family because everyone likes him and he's an amazing dad, I never told my family or my friends why I called off the wedding."
She then explains, "I made up some lie, and I think that's part of the weight gain too because normally I'm very verbal. I kept it all inside."
Find out what Khloe has to say about Gabriela's struggle in the clip above.
