Video! Mama June Shows Off Slimmed-Down Figure in a Wedding Dress

Reality star Mama June's slim-down is on full display in the latest clips from “Mama June: From Not to Hot.”

In the WE tv docudrama, the 37-year-old is showing off her weight loss journey after undergoing gastric sleeve surgery, and she's already looking like a whole new person.

In a fresh clip, we learn Honey Boo Boo needed to go bridal shopping with dad Sugar Bear's fiancée Jennifer Lamb (the pair tied the knot in February), and Mama June decided to come along.

June takes the opportunity to try on a wedding gown, but the shopping trip seems to take a turn when Jennifer confronts June.

See People's exclusive clip for even more footage of Mama June in the dress.

In another preview, June's trainer Kenya confronts her over using chocolate syrup in her protein shakes. Watch!

“Extra's” AJ Calloway caught up with June's daughter Pumpkin last month. She told us her mom, who is reportedly down to a size 4, is barely recognizable between the weight loss and skin removal surgery. “She had the gastric sleeve, and then she starting lose weight so her stomach fat started hangin' so she got all that chopped off. She got her arms — they call them bat wings — she got those chopped off. Then her neck, double chin started sagging more, so she got that taken off as well… Yeah, she looks really good.”
