Dance Moms star Abby Lee Miller is having as much fun as she can before she gets locked up. 

Entertainment Tonight reports that the 50-year-old dance instructor, who was sentenced to a year and a day in prison for bankruptcy fraud and concealing money earned abroad, was recently seen partying at the E! premiere of What Happens at the Abbey.

"She held nothing back when the topic of her sentencing came up," a source dishes.  

She told one person, "I made a mistake and now it’s time to pay the price."

She dished on how she made mistakes with her finances and said she would have done things differently. 

But she said she was refreshed and ready for her "stint in the pen." 

The insider goes on to say that Miller spent some of the evening chatting with a "hunky male model" at the bar.
