Bethenny Frankel and Carole Radziwill's Friendship Is Over! Is Tinsley Mortimer To Blame?

Another friendship bites the dust in the Real Housewives world!

Carole Radziwill allegedly ended her friendship with Bethenny Frankel during the filming of the tenth season of The Real Housewives of New York City.

The two have been BFFs ever since Bethenny returned to the show in season 7 and developed a very close relationship off camera, with Carole even appearing on Bethenny's currently airing spinoff, Bethenny & Fredrick.

Apparently Carole was training for the New York City marathon while Bethenny was focused on her B Strong charity work, which caused the two to drift apart.

Sources are also saying that Carole begin to stick up for newbie Tinsley Mortimer against Bethenny, who became jealous of the former socialite taking her place as Carole's bestie.

The friendship drama allegedly caused Bethenny to try and quit the show several times during filming because she felt many of the women were against her. Word on the street is that the cast have grown tired of her abrasive personality and are letting her know it. I wouldn't be surprised if the Skinnygirl didn't return for season 11.

In the trailer for the upcoming season we see the two discuss the break in their friendship, so we will have a front row seat to all the drama. Something tells me it won't be as dramatic as Bethenny's feud with Jill Zarin.

The Real Housewives of New York City airs April 4th of Bravo!
