Abby Lee Miller is back for season 8 of Dance Moms after a tragic year which included an eight-month stay in prison and a cancer diagnosis that left the former dancer wheelchair-bound and fighting for her life. Abby Lee is back and more determined than ever with a new elite dance team that she will train for competitions. The infamous dance teacher pleaded guilty to multiple counts of fraud, including bankruptcy document fraud, concealment of assets, and failure to declare the $150,000 plus of Australian currency that was brought into the states.
