Abby Lee Miller Gets Mani and Pedi Ahead of Prison Time

Abby Lee Miller nails it when it comes to pampering herself.

The former "Dance Moms" star parked her ass on a comfy chair for a 3-hour mani/ pedi session Thursday in L.A. just days after she was slapped with a 366-day prison sentence. She was convicted on 20 counts of fraud for trying to hide $755k in earnings from the gov.

She seemed unfazed though ... Abby -- who will report to a federal facility near L.A. in about a month and a half -- also gave her future inmate pals a heads-up about her boozing etiquette.

Warning to Abby: the warden frowns upon that kinda thing.
