Bad Blood: Bethenny Refused To Film With Nemesis Jill On 'RHONY'

Six years after she said farewell to The Real Housewives of New York, Jill Zarin has returned to the Bravo hit 9th season — but not everyone is happy.

Though the 53-year-old taped just one episode, her best friend turned nemesis Bethenny Frankel, 46, refused to film with her, RadarOnline.com can exclusively reveal.

"Bethenny has made it clear that if they are tempted to take Jill back full time, she will quit the show," a show insider told RadarOnline.com. "It's either her or Jill!"

Instead, Zarin filmed with LuAnn de Lesseps, and also will appear in footage from the former Countess' wedding to Tom D'Agostino — which Frankel, of course, was not invited to after she exposed the groom's cheating.

Though Frankel retains far more screen time than her enemy, she's still furious that Zarin is featured in the explosive new season trailer.

"She's livid that Jill is trying to steal the spotlight," the insider added. "She had to go naked and make out with Sonja Morgan to get any attention."

Of course, Frankel has plenty of animosity closer to home. As RadarOnline.com previously reported, her ex-husband Jason Hoppy was arrested and charged with stalking and harassing the reality star in January.

"I will destroy you," Hoppy reportedly told his ex in a fight at their daughter Bryn's school. You can get all the lawyers you want. You've been warned."
