After her successful gastric bypass surgery, Mama June still has to lose some weight. In the new episode of her reality show "Mama June: From Not to Hot", the 37-year-old, whose real name is June Shannon, arrives home after the surgery feeling "five months pregnant."

But she still has got a lot of work to do to lose more weight. And to motivate her, her niece Amber gets Mama June a size 4, red-hot "revenge dress" as a little "welcome home present." Amber explains, "This is for Sugar Bear's wedding." Amber wants Mama June to wear it to her ex's wedding. "This is what you're working towards. To go, 'ooh, baby baby, look at me,' " she encourages Mama June.

"I'm a 22/24 right now. This is like 20 sizes smaller than me," Mama June expresses her hesitation. But she's up for the challenge. "You're going to look better than the bride," Amber says. Mama June adds, "Oh, I'm going to look better than her any damn way. Any day of the week."

To achieve her goal, Mama June has to change her eating habit. During a visit to her doctor's office, Dr. Michael Feiz, the surgeon, examines the incision marks before telling her that she will have to take time easing back into eating solid foods.

When the doctor tells Honey Boo Boo that she needs to change her diet too, the 11-year-old isn't thrilled at all. "Like, I have no idea what this man's talking about," the former child beauty pageant contestant tells the camera. "Mama's on this diet, but I'm not, boo boo. I like my curves. ... I mean, seriously, this dude is really crazy."

"Mama June: From Not to Hot" airs Fridays at 10 P.M. ET/PT on WE tv.
