EXCLUSIVE VIDEO INTERVIEW: Hailey Glassman Gives Deposition, Says: "Jon Is A Monster"

Jon Gosselin’s embattled girlfriend, Hailey Glassman, was deposed on Monday by lawyers for TLC and got a painful surprise – confirmation that her boyfriend cheated on her.

In an exclusive interview with RadarOnline.com after the deposition Glassman had only harsh words for Jon and called him “a monster.”

She was the third witness deposed by TLC in their breach of contract lawsuit against the Jon & Kate Plus 8 star.

“Back in June, Jon came to me and said he had a friend who felt horrible for me and wanted to do a ‘defending Hailey’ article,” she explained.

“I think back now and say to myself, ‘Hailey, you should have been smarter.’ I mean they told me, ‘Kate Major is going to pretend to be Jon’s girlfriend so they can take the heat off of you’, and I was like, ‘great! Ok, thank you!’”

But photos of Major and Jon together made her feel the “ultimate betrayal.”

RadarOnline.com has learned that Jon’s legal team did not have a lawyer present at today’s deposition, an unusual move.

Hailey says she told TLC’s Lawyers that she never discussed business deals with Jon and that she was shocked to read reports that she was in on several money making ventures with the reality dad.

“Anyone with a brain can guess that he did stuff outside his contract,” she admits. “He couldn’t do anything without TLC’s approval, we all know that. But he didn’t discuss business deals with me.”
