Jon Gosselin’s apartment in New York City has been vandalized, UsMagazine.com confirms.

The reality star, 32, found his bachelor pad burglarized and ransacked when he returned on Saturday after spending Christmas with his eight children in Pennsylvania, his rep tells Us.

“This is no minor incident,” Gosselin’s rep tells Us. “The police are investigating. He walked into his apartment and it was a disaster. The couch was cut up, his kids’ Wii is missing, his blu ray DVD player is gone, the pots and pans are gone, the couch was sliced up, all of his clothes and shoes are all sliced and torn up. And the knives were left in there.”

According to a source, there was $100,000 worth of damage. In addition, a source claims the word “cheater” was carved into the bed headboard and that a butcher knife was used to slice open the mattress.

Another source adds that there was a note on the counter with a knife sticking through it with the signature of what appears to be that of ex-girlfriend Hailey Glassman.

“Is it convenient that Hailey was just there and moved out this week?” the source says. “Everything was fine, they were friends, talking from time to time, him and Kate are cool and he has to come home to the city to this? Who else would do this? It’s sick, like a case of Fatal Attraction.”

Although it is still unclear if Glassman, 22, ransacked the apartment, she posted her frustration about her living situation with Gosselin on Twitter Friday.

“FYI That apartment everyone calls Jon’s apartment was my apartment as well,” she Twittered. “We split rent! He’s been living off my family and I.”

She also posted that her family “found out a week ago he’s been pocketing our rent money ‘n not paying the rent!”
