Kristen Doute said her co-star Jax Taylor was 'not unfaithful' to Brittany Cartwright on Tuesday's episode of Watch What Happens Live with Andy Cohen on Bravo.

'He was not unfaithful for sure,' Kristen, 41, said. 'And I think Brittany has been pretty public and honest on her podcast, doing press, on WWHL, it was just that she was unhappy. He wasn't treating her as well as he should. He was speaking down to her and it was just turmoil over years.'

'And they weren't banging,' Andy, 55, said.

'And they weren't banging,' said Kristen, who stars with Jax on the spin-off series The Valley.

Kristen while starring on Vanderpump Rules had an affair with Jax while she was in a relationship with co-star Tom Sandoval, 41.

Kristin Cavallari's new boyfriend Mark Estes along with the other Montana Boyz served as bartenders on the show.

In a game of agree or disagree, Kristen and Tom Schwartz, who was also on the show, both said they disagreed that Jax and Brittany would be getting back together.

One viewer asked Schwartz, 41, why he felt comfortable being public with his new girlfriend Sophia Skoro, 23, but didn't feel that way when he was with Jo Wenberg.

'During that time my life was so tumultuous and I just wanted to hide in my little hermitage,' Schwartz said. 'I had some minor PTSD. Yeah I wasn't in any place to be in a conventional relationship.'

Schwartz said he had been with his current girlfriend for five months. 

Andy asked Kristen if Luke Broderick was the right guy for her and she said that he was.

Andy asked whose side they were on about Scheana Shay's diss track about Sandoval.

'I got to go with my boy Sando because he's got nobody in his ring,' Schwartz said.

Andy asked Schwartz if he believed that Rachel 'Raquel' Leviss and Sandoval were truly in love.

'There's a fine line between love and infatuation but at one point in time I heard it from both their mouths,' Schwartz said. 'They were in love.'

'I think it was infatuation,' Kristen said.

Andy then asked Kristen what she thought about Sandoval's suggestion about being roommates with Schwartz.

'No,' Kristen said.

Andy asked the audience which Vanderpump Rules guy they would want as their sperm donor and James Kennedy won with Schwartz in second.

Andy then played a game with Kristen asking her what she regretted. He first asked her if she regretted lying about hooking up with Jax Taylor.

'Yes,' Kristen said.

'Do you regret bringing Miami Girl to SUR to confront Sandoval?' Andy said.

'There's a fine line between love and infatuation but at one point in time I heard it from both their mouths,' Schwartz said about Tom Sandoval and Rachel Leviss. 'They were in love'

'I think it was infatuation,' Kristen said 

'No,' Kristen said.

'Do you regret punching James [Kennedy] in the parking lot of Scheana [Shay's] wedding?' Andy asked.

'No,' Kristen said.

'Do you regret staying with Tom Sandoval for six years,' Andy said.

'Yeah, probably,' Kristen said.

Schwartz said he met both his ex-wife Katie Maloney and Jo Wenberg through Kristen. Schwartz said he didn't think he led Jo on and that it was a mutually beneficial super fun relationship.

'I think she's beautiful and she has a spunk. She has this zany kind of energy that I always found appealing,' Schwartz said.

Schwartz said Katie saying Jo had 'crackhead energy' was 'egregious.'

'She's a darling,' Schwartz said.

One viewer asked Kristen how she planned to raise a child if she and Luke were in separate states.

'When we are pregnant and actually having a child and raising it we will not be in separate states,' Kristen said.

One viewer said they thought Kristen and Jax would make the perfect couple.

'No, I can't even think it,' Kristen said.

Andy asked Schwartz if Katie had met his new girlfriend Sophia.

'She is aware of her and said something really sweet about her,' Schwartz said. 'Katie was lovely about Sophia.'

Kristen added that she felt this season that Sandoval's apologies were sincere.
