An ex "Buckwild" star is behind bars for the holiday -- finally serving her sentence for a DWI arrest from nearly 2 years ago.

Law enforcement sources tell us Ashley Whitt turned herself in to the Pitt County Detention Center on Friday to begin her 30 day stretch in the lockup. Cops busted her in Greenville, NC back in May 2014.

It's unclear why the case took so long to be resolved.

A lots changed since Ashley's big MTV debut back in 2013. Or maybe not much at all ...
