"The bar was wild! Everyone there appeared to be in their 20s-30s.

"It did not seem like a place Christine would even step foot in!" the insider noted.

"There were girls dancing on the bar and a lot of inappropriate things going on inside."

The source continued: "The emcee was telling one girl to sit on another girl's face!

"The emcee also made a comment to another girl on the bar, like, 'Make her wet!' and 'I want you to show me how you ride it.'"

'WILD' NIGHT OUT

With music like Black Eyed Peas' My Humps playing in the background, partygoers at Coyote Ugly were seen taking body shots and drinking cocktails from extra large plastic cups, while girls danced on one another.
