Things are getting uglier and uglier between once-attached Jon Gosselin and Hailey Glassman.

Glassman, 22, has filed a harassment complaint with the NYPD, her attorney tells the New York Post. "The document speaks for itself," Stephanie Ovadia says; the complaint also alleges verbal abuse.

Gosselin, 32, allegedly slammed Glassman against the wall of the Manhattan apartment they share. What set him off? "A picture of her kissing another man," a source claims to the Post. That third party would be boxing promoter Damon Feldman, who Glassman met when she refereed at a recent event at a Pennsylvania hotel.

The former reality dad has denied the charges via his attorney Mark Heller, who told the Post, "Jon is a lover, not a fighter...He's been rumored to steal a kiss here and there, but he has never been accused of landing a sucker punch."

Glassman has been issuing denials herself lately. She has debunked accusations that she ransacked her famous ex-boyfriend's NYC apartment over the holidays. Gosselin reportedly returned to his pad Dec. 26 to find his pad burglarized and trashed -- with a nasty note from Glassman stabbed to their dresser with a butcher knife.

Glassman admitted to writing the note (she called him a "lowlife") but called the rest of the claims "a huge publicity stunt" through her attorney. "Somebody is trying to frame my client," attorney Anand Ahuja said in a statement.
