NEW YORK (AP) — Jon Gosselin's post-Kate relationship isn't going too well — and that's according to his new girlfriend.

Hailey Glassman tells the syndicated television magazine show "The Insider" that the one-time reality TV dad takes out his anger on her. She says he throws "mantrums."

Adds the 22-year-old: "He's like Jekyll and Hyde. But I still love him."

In a statement to the show, Gosselin says he regretted "any pain that my actions have caused her" and that he was committed to making things right with Glassman, his ex-wife and kids.

Gosselin, who filed for divorce from wife Kate in June, was part of the TLC show "Jon & Kate Plus Eight," chronicling their struggles raising eight children.

Glassman spoke to "The Insider" in a two-part interview airing Thursday and Friday.
