Lawsuit -- Dr. Phil Trapped Me, Touched My Boob

Dr. Phil is being sued by a woman who claims the TV shrink held her captive inside his production offices, forced her to stare at a naked man -- and then grabbed her left breast.

According to the suit, filed today in L.A. County Superior Court, a woman named Shirley Dieu claims she went to Phil to seek therapy in 2007 -- but instead she claims the doc tried to "brainwash" her and force her to endure all sorts of physical and emotional abuse.

In the docs, Shirley claims Phil forced her to "be in the same room with a completely naked live man while he exposed his entire naked body, genitals and all."

Shirley alleges she tried to escape the building, but "was blocked by the staff to prevent her from leaving."

In the docs, Shirley also claims Phil "touched her left breast during her therapy session."

Shirley also claims Phil lied to her about being a "real" doctor -- alleging that the TV shrink "is not licensed to practice in the state of California."
