When asked whether there's even a slight possibility she'd consider taking part in the next season, she revealed she's officially quit.
"They have made it pretty impossible for me to go back, frankly. So... no."
Vanderpump stopped filming with the ladies following an explosive argument with her former best friend, Richards.
"I just felt very emotional, very raw…I thought I've been through this on season four, I've been through this on season six…It's an easy accusation to mistake," she said on Watch What Happens Live with Andy Cohen about not filming in large groups after the fight.
While her co-stars refused to believe she had no hand in leaking a story to the press about Kemsley and the adopted puppy she gave up after it bit her child, a lie detector test Vanderpump took on the after show proved her innocence.
"When John Sessa suggested, ‘Why don't you take a lie detector test?' I don't think anybody would volunteer for a lie detector test if they were guilty, so I was happy to say yes. It seemed kind of intriguing," she said. "I think they [the cast] should all take lie detector tests," she added. "I think you should have the reunion and have each and every one of them wired up. How about that? I've done that, can you?"
