Gosselin's girl refs girl-on-girl boxing, wants him out of her life.

Hailey Glassman, on-again, off-again girlfriend of Berks County baby daddy Jon Gosselin, will referee the girl-on-girl matches Dec. 18 at the Philadelphia Airport Ramada during the next Celebrity Boxing event.

She might not have any fighting experience, but she might soon, after hearing Monday that Gosselin cheated on her. She learned that while being deposed by lawyers for TLC, which has sued Gosselin for breach of contract.

Glassman, 22, who shares an apartment with Gosselin, told RadarOnline, "He became a monster. He's a master manipulator and a compulsive liar." She said that although they do live together, she wants him out of her life.

She'll oversee several female fights at the Celebrity Boxing event, which features briefly emasculated John Wayne Bobbitt against South Philly's Tony Fusco in the main event, and several bouts with real fighters.

Tickets are available by calling 800-677-8499 or at the door. Glassman and the female fighters will attend an open-to-the-public press conference at 7:30 p.m. Tuesday at Grey Social (132 Chestnut), where Celebrity Boxing Federation promoter Damon Feldman, just profiled in Philadelphia magazine, will be on hand.
