Jax Brings Scheana to Tears in Explosive 'Vanderpump Rules' Reunion Sneak Peek: 'Why Is This Harder Than My Divorce?'
40 Worst Celebrity Feuds of All Time

"You can't even keep a boyfriend for more than 5 minutes," Jax fires at Scheana in emotional confrontation.

Jax Taylor and his "Vanderpump Rules" co-star, Scheana Marie, have been at odds all season long -- and things definitely don't ease up come reunion time.

On the "Vanderpump Rules" Season 6 reunion -- which Andy Cohen teased on Monday's "Watch What Happens Live" -- Andy asks Jax what he thinks about Scheana's claim that he feels threatened by her then-boyfriend, Rob Valletta.

"OK, cool. That's great. How'd that work out for you?" Jax says sarcastically, looking right at Scheana.

"F-ck you, Jax!" a tearful Scheana fires back. "F-ck you for saying that!"

"You didn't even call me when my father died!" Jax yells back.

As Scheana gets up to excuse herself from the group, Jax continues to take digs.

"I had two ex-girlfriends and a girl who hated me show up in Michigan without even asking, and you can't even give me a f-cking phone call?! F-ck you!" he says. "You can't even keep a boyfriend for more than 5 minutes!"

Cameras follow Scheana as she walks back to her dressing room to get her makeup touched up. "Why is this, like, harder than my divorce?" she says sobbing.

Earlier in the season, Rob told Jax that he didn't use the "L" word with Scheana. Jax later told Bravo cams, "From what Scheana tells me, they say 'I love you' every day. It's not my business, it just seems like one person wants it a little bit more than the other person."

Scheana was livid when she found out Jax was trying to "sabotage" her relationship, so she made it her mission to reciprocate.

The "Vanderpump Rules" reunion begins Monday, May 7 at 9 p.m. on Bravo.
