The Here Comes Honey Boo Boo matriarch has filmed scenes for the new series of the extreme surgery show, following two doctors as they try to correct drastic surgeries gone wrong.
Her Botched role was unveiled by Entertainment Tonight, after the show's Kevin Frazier bumped into Mama June at the airport and she spilled the beans.
Kevin uploaded a selfie to the pair to Instagram with the caption: "Look who was on my flight. She's in town to shoot an episode for the show Botched. She's lost so much weight she is now gonna get the extra skin removed."
Other celebrities to have appeared on Botched include Celebrity Big Brother's Farrah Abraham, Playboy twins Kristina and Karissa Shannon and ex-Baywatch star Nicole Eggert.
Mama June and daughter Honey Boo Boo, real name Alana Thompson, embarked on a weight loss regime last year after appearing on US TV show Doctors, where their diets were analysed.
In May, Mama June revealed she'd lost around 45lbs in one month, while little Honey Boo Boo was down 8lbs in the same period.
Here Comes Honey Boo Boo was cancelled by TLC in 2014 following claims Mama June used to date a man found guilty of child molestation. She denied this and the man also denied any romance.
