'Party Down South' Star -- VIDEO Captures Burglary

TMZ just got VIDEO OF the "Party Down South" star who was busted Sunday in Louisiana for burglarizing a car ... and it's clear this is not a drunken escapade ... it was coldly premeditated.

Check out Lyle Boudreaux scoping out the car. He seems to know it's unlocked and opens the door without hesitation and makes a beeline for the driver's purse. He then takes her credit card out of her wallet and prances away ... not looking drunk at all.

Boudreaux was nabbed in a nearby bar after using the credit card to buy drinks.
