Dr. Drew On Call

Driven by current events, "Dr. Drew" on HLN focuses on the human - and human behavior - at the center of the story.

Tonight: Is Newt Gingrich's private life any of our business?

The Republican running for president was asked some particulars about a previous marriage last night. He responded by ripping into the media, drawing cheers from the partisan crowd. He admits to cheating on his spouse.  His ex-wife says he wanted an "open" relationship. What's fair game when it comes to a politician's private life? Dr. Drew and his guests have something to say about that.

Plus, a dozen teen girls have developed a condition that baffles experts. They suffer from unexplained physical tics and verbal outbursts. We'll meet one of them and hear about her experience first-hand.

Tonight! Saluting our troops with 'Grey's Anatomy' star Kevin McKidd

Paging Dr. Owen Hunt! Actor Kevin McKidd plays a doctor who experienced post-traumatic stress disorder on the hit TV show. He has taken a personal, off-screen interest in the condition, and helping those with it. He joins Dr. Drew for a frank discussion about PTSD. Now that the Iraq war is officially over, many more servicemen and women are likely to experience the condition. We'll meet a real-life wife who tells us about the toll it can take on caretakers.

And Dr. Drew and his guests will discuss the testimony in the Penn State child sex abuse case. The man who claims he saw Jerry Sandusky assaulting a boy, speaks under oath, at a prelimary hearing.
