When the teaser for Dina Lohan's interview with Dr. Phil hit the web last week, it was thought that she might have been drunk or high or something during the taping.

Nobody knows for sure what was going on with her, but the interview, which aired yesterday (Sept. 17) was definitely strange. To wit, she was so cantankerous that Dr. Phil started going in on her.

“Can I ask you some questions, and you answer them, not in television speak but just answer them honestly?” he pleads. "You spent more time talking about cameras— 'Are we rolling?' That's my business. We’re not here about my business, we’re here about your life. What you have done is distinguished yourself in the negative, you have come on here and been phony and inauthentic."

At that point she just decides to start giving him the finger. Watch the clip at Radar Online.
