ET spoke with June in April, who said that her weight was "in the 160s" -- and that she will "never go back to what I looked like."

"I will do whatever it takes," she added, revealing that she spent "well over $50,000" on surgeries like gastric sleeve and a boob job. "You have to exercise and you have to maintain [this lifestyle]. A lot of people think that when you have surgeries, that it's just -- nothing else has to be done. And that is not the case. It is a live and learn thing."
