Wow, Mama June — is that really you?

The former Here Comes Honey Boo Boo star promised fans that they would see a weight loss transformation on her new show Mama June: From Not to Hot — and she definitely delivered! The reality star lost 300 pounds on her weight loss journey and she debuted her new size 4 frame on last week’s episode of the hit WEtv series.

“Introducing the new me,” the 37-year-old tweeted as the episode aired. “I’ve been through a long road, I’m so proud of where I came from.”

That long road started after she returned home from filming Marriage Boot Camp: Reality Stars with her ex Sugar Bear — where he revealed the shocking bombshell that he cheated on her with men and women throughout their 11-year relationship. When they got back to Georgia, Mama June kicked him to the curb.

But when he suddenly announced that he was going to get remarried to Jennifer Lamb — one of the women he met while he was still with June — she decided that the best way to get revenge on her ex is to show up to his wedding with a smoking hot new body. She underwent gastric sleeve surgery in order to kick start her weight loss and she worked closely with personal trainer Kenya Crooks to shed the pounds.

After all of her hard work, Mama June went from 300 to 190 pounds. She went under the knife two more times to remove excess skin and she also got a tummy tuck and a breast lift. Once she fully healed from her surgeries, she debuted her new size 4 body with a photo shoot — and her own daughters didn’t even recognize her.

But her journey isn’t over yet — and it seems like she might have gotten her revenge body for nothing. During last week’s episode, Jennifer Facetimed Alana “Honey Boo Boo” Thompson — whom June shares with Sugar Bear — and asked the 11-year-old to disinvite her mom from their wedding.

“Mama’s not invited to the wedding? This is everything she’s been working towards,” the former pageant queen lamented.
