The Real Housewives of New York City's Bethenny Frankel isn't letting go of her feud with Kelly Killoren Bensimon.

"Bethenny is writing a new book that will deal with their animosity," says an insider close to the Naturally Thin author, 38. "Instead of food, this time it'll be about romance and money and friends and getting rid of all those voices in your head that are trying to tear you down. It's going to be a hot read."
