TMZ obtained video of alleged "Bachelor" beater Mary Delgado at the Pinellas County Sheriff's Department, while she was patted down and changing out of her brown jacket into an ever-so-sexy, bright yellow, jail-issued top.

Delgado was arrested in Tampa, Fla. last week for alleged domestic battery, after punching former "Bachelor" contestant Byron Velvick. Cops say alcohol was a factor.
