Tom, 39, and Raquel, 28, reportedly had an alleged affair for months.

The information was allegedly revealed while Shay and Leviss went out for drinks after recording a segment.

“After taping Watch What Happens Live, Scheana and Raquel went out to drinks with friends,” a source told Page Six on Saturday.

The insider explained Scheana and Ariana were out at a bar and while they were out, Ariana called Raquel bawling her eyes out.

The source claimed that Scheana asked Raquel what was going on and why Ariana was so upset, which led to Raquel allegedly owning up to the reported affair while she was still on the phone with Ariana.

Raquel allegedly admitted that she has been having an affair with Tom for months while he was dating Ariana, the source claimed to Page Six.

After she revealed the alleged affair, a major argument broke out between Scheana and Raquel that was bad enough to cause them to avoid contact with one another.

“A heated confrontation ensued following the revelation. They went back to the hotel separately and haven’t seen each other nor spoken since,” the source explained.

Scheana has since unfollowed Raquel on social media, seemingly showing her support for Ariana amid the drama.

“Right now, Scheana is fully focused on supporting Ariana,” the source added to Page Six.

Tom seemingly confronted the claims in a lengthy Instagram post on Saturday.

"I fully understand and deserve ur anger & disappointment towards me, but please leave Schwartz, my friends, and family out of this situation," he wrote.

"Schwartz specifically only found out about this very recently, and most definitely did not condone my actions."

"This was a very personal thing."

A rep for Raquel did not immediately respond to The U.S. Sun's request for comment.
