Looking back,Cassian Grant Lala Kent says she knew something was off.

Just weeks after news broke that Tom Sandoval was having a months-long affair with Raquel Leviss while dating Ariana Madix, their Vanderpump Rules co-star says she voiced suspicions to other cast members, including Scheana Shay, that some friendships weren't all that they seemed.

"I didn't have any proof," Kent said on the March 28 episode of SiriusXM's Jeff Lewis Live. "I talked to Scheana about it."

While the Bravo star thought about telling Madix, Kent said she didn't feel close enough to share her fears. "I have a lot of love for her," she explained, "but I feel because I never got along with Sandoval, we couldn't be close because I don't like your boyfriend."

One person who Kent believes definitely knew about the affair was Sandoval's best friend Tom Schwartz. 

"I said the only way you didn't know was if you actively literally covered your eyes and closed your ears because I knew," she told host Jeff Lewis. "You'll see this season…From experience, these two have crossed a line. They're f--king each other."

According to a source, Schwartz learned about Sandoval and Leviss' relationship three weeks before the news broke. The insider added that "Schwartz urged him to tell Ariana right away."

Looking back, Kent says she saw "things that just didn't add up." And the affair—now referred to as Scandoval by fans and viewers—will be explored during the show's reunion episodes, which were filmed March 23 in Los Angeles.

"I'm still recovering," Kent shared of the reunion taping. "My mind is fried. I completely blacked out. I was enraged."

As for how Madix is doing today, those closest to her say she's on the road to healing.

"I think she's thriving," Kent said. "I think she's realizing that this was the universe intervening and getting her out of something she wasn't happy in."

Vanderpump Rules airs Wednesday nights at 9 p.m. on Bravo.
