One contestant is revealing a very personal story tonight.
On Revenge Body With Khloe Kardashian, contestant Jessy tells host Khloe Kardashian about her past drug addiction and how it coincided with her weight loss struggle.
"At your smallest, were you ever small in a healthy way?" Khloe asks Jessy in the clip above.
"I mean my smallest was when I was on drugs," Jessy admits. "I never liked being high, I hated being high, I loved being skinny…that's the entire reason I did it."
Jessy goes on to explain, "I started doing hard drugs when I was 12, tried everything, by the time I was 15 I discovered meth and I was so skinny. It's the only time in my entire life I remember my mom being off my back."
Her drug addiction then escalated to a point where she was homeless for a few months, and that's when Jessy decided she couldn't "do this anymore" and was ready to start a new chapter in her life.
Watch the clip above to see Jessy tell Khloe about her past and then watch tonight to see Jessy start her Revenge Body journey!
