In an exclusive sit-down interview with ET's Cameron Mathison, the 50-year-old dance instructor revealed that she's still feeling some bitterness towards the Dance Moms producers, and claims that they are partially responsible for "keeping" her overweight. Now that she's off the show, Miller has decided to get gastric sleeve surgery, which will remove 80 percent of her stomach.
"If I was trying to be vegan, [they would] hand me a hoagie sandwich or Italian sub from somewhere," she said of her former co-workers. "I'm like, 'What is this, lunch meat? I can't eat this!'"
In a way, Miller is using the surgery, which was performed by Dr. Michael Russo at the Smart Dimensions Surgical Center, to get a revenge body. "I hate what I look like on TV and I want to look better and nothing makes the mothers more jealous," she explained. "There's your motivation. Payback's a b**ch."
Miller also admitted that she is nervous about the surgery. "I think when I'm going into surgery, I'm scared, I'm nervous but I don't really have anyone counting on me," she said, wiping away her tears. "I'm an only child. I'm not married. I don't have any kids, so there's nobody freaking out if something happens to me."
Clearly emotional, Miller added, "There's nobody outside to see if I'm gonna make it or not."
