Ariana Madix Was 'Blindsided' - But Tom Sandoval & Raquel Leviss 'Full-On Affair' Has Been Going On For MONTHS!

More details have come out about the Vanderpump Rules cheating scandal, and they are rough for Ariana Madix.

As we’ve been reporting, Ariana broke up with Tom Sandoval this week – and the reason has Bravo fans freaking out. TMZ was the first to report on Friday that the 39-year-old restaurant owner cheated on his longtime GF with none other than their co-star Raquel Leviss. But it wasn’t just some one-time hookup either. Nope! This apparently has been going on for a while now!

According to sources spilling to Page Six, the castmates were having a “full-on affair!” One insider revealed Raquel and Sandoval have been “communicating inappropriately for months” – and they “want to be together” now. OMG!!!

The outlet reported that Ariana found out about the TomTom co-owner’s infidelity when she was attending her ex-boyfriend’s show with his cover band, Tom Sandoval & the Most Extras, in Los Angeles on Wednesday. To learn about your man’s affair while being a supportive girlfriend at his band’s event?! Even worse than we thought…

As for claims the exes were on the outs for a while? A source told the outlet that Ariana was actually “blindsided by the cheating.” Another insider further noted there was zero indication that the former couple was having problems before that, explaining:

“Ariana and Tom have been affectionate in public recently. Ariana had no idea there were any issues.”

Beyond being hurt by her longtime partner, the source shared that Ariana feels “betrayed” by Raquel since she considered her a “friend” and had even supported her during her difficult split with former fiancé James Kennedy:

“Ariana is heartbroken. Ariana was there for Raquel during the James [Kennedy] breakup.”

Talk about breaking girl code…

We would not blame her for being PISSED at Raquel right now. But at this time, neither Raquel, Ariana, nor Sandoval has spoken out to either confirm or deny the affair allegations. However, Ariana did delete her social media accounts on Friday — a pretty obvious sign that something bad is going down right now. Of course, we could be getting their firsthand responses to the situation soon enough…

While season 10 of VPR is currently airing, TMZ reported that producers fired up the cameras to film the cast’s reactions to this bombshell and plan to include them later in the season. A source close to production also told Page Six:

“The majority of the cast is expected to gather and film tomorrow to share their reactions to Raquel and Sandoval’s affair. Mostly everyone is shook and completely heartbroken for Ariana.”

“Mostly everyone is shook…” We would not be surprised if Tom Schwartz knew his best friend and business partner was also hooking up with Raquel. Or was their fling meant to divert any possible attention from her and Sandoval’s affair??? Who knows?? But what we do know is this situation is beyond messy!
