When The Beautiful Life actress, Mischa Barton, hit up the party on Friday thrown by DGI Management’s Yoni Goldberg, she got a visit from the ghost of Halloween past.

Barton’s ex, Brandon Davis, was also in attendance at the soiree and it seems that the erstwhile couple’s claim to have stayed “good friends,” is a bunch of BS.

A witness tells Page Six, “They saw each other and then spent the whole night on opposite ends of the party. They didn’t seem interested in saying hello, and Mischa appeared a little wobbly,” the snitch reports.

Well, I think you’d be a little wobbly if faced with this.
