The longtime housewife, 59, announced her departure on Thursday.
Rinna told RadarOnline.com: "This is the longest job I have held in my 35 year career and I am grateful to everyone at Bravo and all those involved in the series. It has been a fun eight-year run and I am excited for what is to come!"
Her team also confirmed the news, saying, "After taking the time to weigh her current options and business obligations, Lisa and Bravo have discussed and mutually decided that she will not be returning to RHOBH."
Rinna's exit comes months after we exclusively reported that she was renegotiating her contract with Bravo. Sources told this outlet that Rinna was demanding $2 million a season, which would make her the highest-paid Housewife of any franchise ever.
“At this point, Bravo needs Lisa more than Lisa needs Bravo. She was a star before Bravo and will be a star long after Bravo too,” insiders spilled in September.
The source continued by claiming Rinna wasn't scared of walking away if she didn't get what she wanted.
“Lisa knows her worth and knows how to negotiate. Only Lisa is willing to call their bluff and walk away if she doesn’t get the deal she wants. While the other ladies are frightened to upset Andy (Cohen), Lisa is fearless. She’s not frightened of him or anyone else," they told RadarOnline.com.
The news comes weeks before filming is set to begin.
RHOBH was put on pause as both the cast and the show's production team "needed a break" after possibly the most dramatic season in Housewives' history. In December, insiders spilled to RadarOnline.com that filming is set to begin toward the end of January; however, cast members had not yet received contracts.
Rinna might be the first RHOBH star to announce her departure, but she might not be the only one.
One source told us the cast felt like Kathy Hilton was "being wishy-washy" about her return; however, with her archenemy now booted out of the way, there's a better chance she might come back following a combative season with Rinna.
