Jon (left) and Hailey (far right) arrived late night (3 a.m.) to the Lexington Bar and Grill.
The two were accompanied by a friend of Hailey's (brunette) and their body guard (center).
John bought a round of Southern Comfort shots for everyone in the bar.
The three were looking intoxicated, though the body guard (who drove the red Escalade they arrived and left in) only drank water.
