Marvel Universe LIVE! Age Of Heroes World Premiere Celebrity Red Carpet EventFormer "Dance Moms" star Abby Lee Miller started her prison sentence Wednesday, but she didn't do it without one last tweet for the road.

The reality TV star, who was was slapped with a 366-day sentence after pleading guilty to bankruptcy fraud, was candid about the fact that she is struggling with her fate. In a tweet that includes a dead Instagram link, she conveyed her distress, and then seemed to defend herself once again.

"Today is going to be a tough day!" she wrote. "Seems as though important facts were omitted from the case!"

In spite of pleading guilty, Miller has argued that she made mistakes. She said she was "not a criminal mastermind" in a June Extra interview, as People reported.

"I listened to the wrong people," she said at the time. "I trusted people."

Whatever the facts, Miller will be behind bars for the foreseeable future, and we expect we'll hear plenty about the experience. The reality TV star reportedly arrived at her check-in point with Lifetime cameras in tow, filming footage for an upcoming special.
