We guess she wasn't indulging in commissary honey buns!

Abby Lee Miller has lost more than 100 pounds during her prison stay, and she showed off her new physique in this new Instagram photo. The Dance Moms star has been serving time for bankruptcy fraud since 2016, but rumor has it her release date is right around the corner.

"Sometimes in life you make mistakes I trusted the wrong people and didn’t pay any attention to things I should of. I’m more than sorry for the mistakes I have made. My world flipped upside down when I had to enter prison. I did so with grace, the stories you read about me been a princess are untrue. I have made friends with both inmates and staff, I’ve tried to better myself, participated in anything offered to me and I am a better person for this experience," she captioned the snapshot.

"All the press stories and speculation are not entirely correct however, I am feeling hopeful but no dates have been confirmed at this time. I am feeling great and ready to turn over a new leaf thank you so much to everyone for your support especially my nearest and dearest I love you all ❤️ ( and yes this is me in prison ) #abbyleemiller #abbylee #dancemoms #dance #aldc," she added.

Going to the slammer is apparently a great weight loss routine!
