Tori and Lisa have been good friends for years, with Spelling starring on Beverly Hills, 90210 and Rinna appearing on FOX's sister series Melrose Place.
Tori would benefit from Bravo's big paycheck, especially since the fate of her current TV project is in question. It was reported that her husband, Dean McDermott quit the couple's controversial docu-series 'True Tori.'
Also, back in September, it was announced that her ABC Family sitcom 'Mystery Girls' was cancelled just after one season.
Just last month, the actress turned reality star shared a photo of herself posing along with Lisa Vanderpump on her Instagram page with the caption, "Always fun running into my friend @lisavanderpump #CocoMissesGiggy #RHBH I'm in NYC promoting #TrueTori 2nite @lifetimetv 9pmEST"
At the moment this is all a rumor, I personally don't see this happening but Bravo sure loves to surprise us.
