Scheana Shay has accused Lisa Vanderpump of 'gaslighting' her for over a decade ahead of the release of her upcoming memoir My Good Side.
The TV personality, 40, worked for the restaurateur in the Bravo series Vanderpump Rules which she starred in for 11 seasons.
However, earlier this year in January, the mom-of-one announced her new book and promised to spill the 'tea' on Vanderpump.
Shay also gets candid about her 2006 affair with Eddie Cibrian - when he was still married to Brandi Glanville. While on the topic, she also alleges that Lisa knew more about the situation than she initially disclosed.
'We all saw it play out on the show when I went up to her and she acts shocked that I was working her party with this guy's ex-wife who I used to date because I didn't know he was married,' she told Us Weekly for a new cover story.
Scheana was referencing to her appearance in past episodes of The Real Housewives Of Beverly Hills - and claimed Vanderpump purposefully put her and Glanville together on screen in order to 'launch her TV empire.'
DailyMail.com has reached out to Shay and Vanderpump's reps for comment.
However, earlier this year in January, the mom-of-one announced her new book and promised to spill the 'tea' on Vanderpump.
The media personality added, 'Now, I feel like she low-key used my real-life pain to launch her TV empire - and what an empire she has.'
Shay - who revealed her husband Brock Davies cheated on her while pregnant -further alleged that it was difficult for her to believe that Lisa had no knowledge of the affair.
'I vividly remember when photos leaked of Eddie and I, there was a magazine being passed around the kitchen at Villa Blanca,' she explained, referencing to Vanderpump's former restaurant.
'She gaslit me about it for a decade instead of just coming to me in the beginning. She doesn't make mistakes. She makes moves and then calls them coincidences.'
Scheana later expressed that she wished the RHOBH star had been 'transparent' with her and admitted she 'always looked up to Lisa.'
'I've always admired her. Now I'm like, "Did I admire her out of fear?" I guess I would've just like to have agency in my own story.'
But Shay explained to the publication that their friendship allegedly began to cripple years after she had been cast in VPR.

'She gaslit me about it for a decade instead of just coming to me in the beginning. She doesn't make mistakes. She makes moves and then calls them coincidences,' Shay added of Lisa
'On season 6 of VPR, when James Kennedy told Katie Maloney that the outfit she was wearing wasn't flattering, I got a phone call from Lisa.'
The reality star further stated, ‘She didn’t want to fire James, so she needed someone to stand up for him [at a staff meeting].’
Earlier this year in January, Shay announced her memoir and revealed that she would not hold back when it comes to her relationship with Lisa.
And in May, Vanderpump herself broke her silence on Scheana’s comments during an appearance on Watch What Happens Live with Andy Cohen.
The TV personality said, ‘Oh good Lord. Well, that’s probably just to sell the book because she hasn’t got anything else to say.
‘Do you know what? I don’t know, I’ve heard she’s said some nasty things. Something nasty recently she said something like, I only call her when I need something. True dat, right?’
She added, ‘I’ve got 600 people I work with. I think the last time I needed her was when I invited her to my house to Teddy’s birthday. So yes, that’s when I called her.’
In her memoir - which hits shelves on July 22 - she also made a startling admission about her affair with LeAnn Rimes’ husband Eddie Cibrian.
Scheana previously revealed that she carried on a relationship with the 52-year-old actor years ago without realizing he was married at the time.
And in an excerpt that was obtained by Entertainment Weekly, she admitted that her judgment was compromised when she was younger, as she never noticed ‘a single red flag’ with Cibrian.
According to Shay, she had just moved to Los Angeles in May of 2006 after graduating from Azusa Pacific University.
The future TV star, who was only 21 at the time, wrote that she hoped to ‘make a name for myself in the entertainment industry, whether that was as an actress, a TV host, or a news reporter.’
Fortuitously, she met a real-life star with some success shortly after she got a job at a ‘private member’s cigar lounge’ that doubled as a restaurant that was regularly filled with ‘every A-list celebrity, director, writer, and actor’ around.
A few months into the job, she allegedly met Cibrian at a Tuesday night poker game, and she claimed he returned weekly for the game.
At the time, he was married to former Real Housewives Of Beverly Hills star Brandi Glanville, whom he wed in 2001 and divorced in 2010.
The future model wouldn't make her big break in reality TV until 2011, when she joined the series as a friend for its second season.
The couple had split in 2009 after it was reported that Cibrian had an affair with the country singer LeAnn Rimes, whom he went on to marry in 2011.

Scheana claimed that her connection to Cibrian grew slowly over time, but she felt there was a spark right from the start.
The idea that Cibrian could be married at the time doesn't seem to have crossed her mind, but she also defended herself because there wasn't an easy way to casually track down intimate details about a person at the time.
This was pre-social media, so it wasn't like he was posting pics of his family in matching pajamas in front of a Christmas tree,' she explained.
Moreover, Shay alleged that Cibrian ditched his wedding ring whenever he went to the Tuesday poker game.
'To be clear, Eddie wasn't my boyfriend (at least not exclusively),' she emphasized. However, she did claim that they began a 'physical relationship' in late 2006.
Another factor that blinded her from realizing that he was married was how they allegedly spent plenty of time in public with friends or on his boat, instead of trying to keep the relationship completely secret.
She added that the 'frightening thing' about the relationship was that she thought she could easily 'end up with Eddie.'
The relationship petered out when Scheana allegedly told Eddie she thought she was too young to be committed to a single person.
Around that time she allegedly began dating the actor Jesse Metcalf, 'the sexy gardener from Desperate Housewives.'
She claimed to have seen him as the title character in 2006's John Tucker Must Die and 'dream[ed]' of dating him - which became a reality in early 2007.

Although she thought he was an 'awesome' guy and respected his focus on his sobriety, they grew apart and she allegedly began seeing Cibrian again.
However, she claimed a coworker later revealed to her that he was married, which she claimed he denied when she confronted him about it.
Scheana explained how she never ended up at Eddie's home, which would have tipped her off that he was married.
Cibrian shares two sons with his first wife Brandi - Mason, 22, and Jake, 18 - and the exes eventually found their way to a friendly co-parenting relationship after his marriage to Rimes.
Shay later married Michael Shay from 2014 to 2017, and she tied the knot with her second husband Brock Davis in August 2021. The couple had welcomed their first child, four-year-old Summer Moon Honey, in April of that year.
Scheana became a main cast member of VPR in 2013 through 2024. But it was revealed late last year that the 12th season of the Bravo series will have an entirely new cast.
She has since made appearances in the spinoff series The Valley - alongside other stars including Brittany Cartwright.
