Barton Blasts Richie

Mischa Bartonlashed out at (now ex BFF) Nicole Richie for severing their friendship, branding "The Simple Life" star as "fickle".

Mischa used to be spotted regularly at the hottest parties Nicole but their relationship has gone cold after Richie stopped returning Barton's calls.

Barton says, "I think of Nicole as a good friend but she hasn't been in touch recently. "It's quite fickle of her."

Does Nicole just drop friends every time she gets serious with a new man? She dropped Paris when she got engaged to DJ AM and now she's dropping Mischa 'cause she's getting serious with Brody Jenner? I love Nicole to death, but that shit just ain’t cool.
