No matter how clean the break-up, no daughter wants to hear that her father still loves her ex. But that’s just want Bill Clinton announced last night at a book party for Chelsea's ex-BF, Ian Klaus.

“I’m biased because I love the author … but I think it’s exceptionally well written,” Clinton said to the crowd.

The P.R. people at Knopf, which is publishing Klaus’s new book, are probably the only ones who don't find her father’s doting inappropriate.

And what does Chelsea Clinton’s current beau, Marc Mezvinsky, think about the relationship? All he would say was his standard, "I'm sorry, I don't talk to the press."

Come on, Marc. You’ll never get a book deal with that attitude.
