Abby Tells All On 'Tough' Day Of Prison Check-In, Goes On Bizarre Social Media Rant

Abby Lee Miller is reporting to FCI Victorville prison today to begin her 366-day sentence for fraud – and she is saying goodbye to her fans with a bizarre social media rant!

"Today is going to be a tough day," Miller, 50, began the now-deleted Instagram post. "Seems as though important facts were omitted from the case! Just wanted to let the world know – moms and girls all made money – Lots of money! #Dancemoms."

The photo is of a check for $35,719.80, which she claims was forged with her signature.

The former Dance Moms star also asks who M, M & M is, as the check was made out to the mystery corporation.

"Whoa that's their profit from one little trip and three little events," she wrote on the check, dated October 7, 2015.

After Miller deleted the odd post, she uploaded yet another slamming music company Jenga Productions.

"I'm fed up with your shenanigans," she fired. "I paid you $30,000 plus extras for 10 songs and I only got 2 - give me my money back!!! I also want the profits to which I'm entitled! You Canceled 3 meetings with my Atty! You have had a year to make this right, time is up!"

Miller is expected to report to prison today. The Federal Bureau of Prisons could not confirm to RadarOnline.com that Miller has checked in. Sources told RadarOnline.com that she is expected to check in by 1pm Pacific Time.

The former Dance Moms star pled guilty to not reporting an international monetary transaction and one count of concealing bankruptcy assets in June 2016.

She was sentenced to one year and one day in prison.

As RadarOnline.com reported, Miller will be strip-searched for contraband and drugs during the check-in process, former inmate Hollie Coulman told RadarOnline.com.

"They will have her go into the bathroom, disrobe and stand over a brown sheet," she said. "She will have to then squat and cough. She will then put her hands together and squat. Then they ask her to open her mouth and shake her hair out. She will have to lift up each breast to show them she is not concealing anything! Everyone has to go through it, and it is incredibly degrading!"
