Jon Gosselin’s New York City apartment was “ransacked” by an unknown burglar who left behind a note bearing the name of the reality star’s ex-girlfriend, reports TMZ.

The former “Jon & Kate Plus 8” star returned to his home to find his pillows sliced to shreds and a note signed “Hailey Glassman” with a knife stuck through it, reports the entertainment Web site.

The apartment is listed under both Gosselin and Glassman’s name and the reality dad is filing a complaint with the police, reports TMZ.

Gosselin, 32, who shot to fame as a reality dad of eight with wife Kate Gosselin, took up with the 22-year-old Glassman a mere three weeks after filing for divorce from Kate this past July.

Glassman and Gosselin called it quits in October.
