Lisa Vanderpump claims she 'knew' castmate's partner was cheating but stayed silent... amid Kyle Richards and Dorit Kemsley marriage splits

For years, Lisa juggled roles on Real Housewives of Beverly Hills and her Vanderpump Rules spinoff.

In March 2023 Ariana Madix and Tom Sandoval's nine-year relationship imploded when it was discovered that he had been having an affair with castmate Rachel Leviss.

Jax Taylor has been accused of cheating on estranged wife Brittany Cartwright as their crumbling marriage unfolds on Vanderpump Rules spinoff The Valley.

However, the British-bred reality television personality did not specify which unfaithful partner she knew about. 

While host Alex pushed for names as she mentioned Kyle and Dorit, the Bravolebrity remained coy: 'No, you're not guessing or doing or saying anything because that's not a headline I'm living with. So, no, it's not either of them. It could be, but it's not.' 

She pondered, 'You know what I find surprising? They're on a reality show and they're living their lives — and of course all marriages have problems — but then suddenly they get divorced but they've been saying, "Oh, love bean. My king. Or my this or my that."

'Life's not like that. You have two imperfect people living together and that's bulls**t.'

Lisa added, 'How many times have you seen this? Especially on that show that I used to be on. How many times where, "Everything's just going great, just fine," and then, "Oh, we're getting a divorce." Oh, OK. Or, "Oh we've separated, we've separated," when it's been going on for months and years.'

And Lisa maintained she had no idea about Sandoval and Leviss' scandal, which later came to be referred to as 'Scandoval.' 

'Oh God, no, no. I didn't know,' Vanderpump said. 'I did say in the kitchen one time, "Ms. Malibu's in the jacuzzi?" And I said, "That's not OK."

'And Ariana was vociferous in saying, "No, no, no. She's my friend. I'm fine with that." And I said, "Well, I wouldn't be fine with that." 

'If I was away on the other side of town and Ms. Malibu was in the jacuzzi with my husband when I was away? No, that's not OK.'

'If I'd known, I wouldn't have been saying that,' she noted. 'And also, I wouldn't have condoned that.'
