Nicole, 25, who has recently begun dating her childhood friend Brody Jenner, 23, has allegedly been receiving “constant�? phone calls and text messages from Adam. Says an insider, “Nicole just wants to move on, but he won’t let go. Nicole thinks it’s unhealthy for them to talk and hopes A.M. will finally just leave her alone.�? The source claims that Richie has even had to ask that security guards in her building keep Adam away from her.

Of course, a rep for 33-year-old Goldstein says, “This whole story is utterly ridiculous.�? And a friend of Adam’s claims, “If anything, it is the other way around. She’s the one who calls him, and he wants nothing to do with her. He is very happy not to be with her and is dating other girls.�?

Reportedly one of those other girls that Adam has been dating is Brody’s ex, Kristin Cavalleri. Last week the New York Daily News linked the two together when they attended the Guess 25th anniversary party. Kristin and Adam were said to have been “cuddling�? at Bungalow 8 that night. Sounds like the drama between this foursome is nowhere near over.
