When the long, long legged American Idol Katharine McPhee was in Washington last week to sing at a youth rally sponsored by Hillary Clinton, all she wanted to do was have a little fun and empower young women to show them they, too, can “shoot for the stars.”

“I love you all,” she told a female Big Head DC operative who attended the event. “You’re great!”

But all was definitely not great after the event when McPhee did local radio show host Kane’s morning show on 99.5 FM (Kane, you’ll recall, unceremoniously replaced the popular Mark Kaye and Kris Gamble morning duo last year). McPhee, you see, was interviewed by intern Ally, and, according to MSNBC, the station had agreed beforehand that McPhee wouldn’t be asked any personal questions.

However, one of the first questions Ally asked the 23-year-old singer was about her 42-year-old boyfriend. She sassily wondered whether having a boyfriend who was so much older hurt or helped the relationship.

Big Head DC has since learned that McPhee is “outraged” and has told friends that she will never do the program again.

Kane, for his part, is sticking to his guns: “Slam us, go-head,” Kane wrote to McPhee fans who have begun to bash the station on their blogs and in the press. “Kat could have had a little more fun with Ally. She could have said, ‘You guys know you’re not supposed to ask me personal questions. What’s wrong with you?’ Rather, she just got mad.”
