Dina Lohan Partying It Up

This is what coke does!

DINA Lohan needs to learn when to call it a night. The soon to be reality wreck hit Monday's "Made of Honor" premiere party with galpals at the Metropolitan Club, where she stayed till the wee hours. "She was dancing, drinking and playing with her hair extensions," said our spywitness. "The hours are going by and everyone is leaving, some people left very late, and she was still there partying, still going. She probably stayed past the staff."
