'Real Housewives of Beverley Hills' star Lisa Rinna is threatening to sue her co-star, Lisa Vanderpump over a reported spin-off show.

On the current season of the Bravo show, LVP was understandably annoyed after Dorit Kelmsley adopted a puppy from her center, 'Vanderpump Dogs' and then gave the puppy away to a shelter just weeks later. The dog eventually returned to Vanderpump's facility.

"I'm a hustler. I make no bones about that. I think you get paid for what you do," the 55-year-old star wrote on Instagram Stories. 

"So my feeling is if we indeed are servicing a spin-off we should be paid for it. If you are going [sic] to use our services without telling us-that we are playing out a storyline to launch a pilot for a new show and you don't compensate us extra for that. Yeah I'm a hustler I get paid for what I do."

She continued.

"So if this indeed becomes another show my lawyer will be calling."

A spin-off has not been confirmed, but Vanderpump's doggie home has been regularly featured on her show, Vanderpump Rules' and is a part of her life. So it's unclear exactly why Rinna would feel that she should sue. Also, 'RHOC' star Kelly Dodd revealed that in their contracts with Bravo, it says that they agree not to sue each other. It's unclear as to whether the RHOBH contact is the same, but Rinna has gone as far as to accuse one of her costars of sniffing coke on the show - she could face some legal action also?
