Pumpkin doesn’t take the news all too well, telling her mother, “I don’t want you to look different.”

While June admits her own neuroses, she remains honest with her daughters, explaining, “I’m scared too. I know that, like, y’all are worried about me not coming back.”

Mama June’s decision to go under the knife comes after months of dedicated weight loss through diet and exercise.

“Honestly, when I first started losing weight, it was just being more active, being busy with the show and doing more things with Here Comes Honey Boo Boo,” she previously told In Touch. “I went from like a [size] 28 to a 16 — and these pants are a little too big.”

In the trailer for the show, it’s clear that Mama June is ready to embrace her new life!

“Goodbye to this old life, goodbye to men who don’t treat me right, and goodbye to this old body,” she excitedly shares in the clip. “When I’m done, I’m not even going to recognize my own self in the mirror. Y’all better get ready.”
