"In the past year, we have seen the impossible become possible," an announcer says in the new video. "Can Mama June actually be a size 4?"

The beginning of the dramatic trailer shows Mama June weigh in at 352 lbs. before a super-cut of her working out, struggling with her eating and having emotional talks with the rest of her family members about undergoing weight loss surgery.

"This surgery is the scariest thing I've ever done," she declares. "There is a skinnier person inside of me."

Throughout the two-minute teaser, the reality TV star looks noticeably more glam and skinnier at points, though it mostly focuses on her struggle to lose weight and the ramping up of her dating life.

"I'm changing my body and my love life," she says as she scrolls through a dating app at one point. "I'm about to start the biggest transformation of my life."

One thing's for sure -- we can't wait to see what she looks like now.
