Katie Maloney picked up on a few red flags while watching Scandoval play out from a “birds’ eye view.”

The “Vanderpump Rules” star said on the “Viall Files” podcast Tuesday that she noticed how “very close” Tom Sandoval and Raquel Leviss were during their affair despite being “on the outside” of their friend group.

“I started realizing … when Ariana [Madix] is not around, they’ll still be hanging out,” Maloney, 36, recalled. “If Ariana chooses not to go to a party or an event, Tom and Raquel will just go together.”

The reality star noted that while it is normal to have “platonic friends … there was something off about the situation.”

She added, “Something reeked of [cheating] to me.”

Maloney claimed that had she been closer to Leviss, 28, and Sandoval, 40, she would have called out their matching lightning bolt necklaces.

“I notice things my friends are wearing, especially something all the time, [and ask], ‘Is that new? What’s the significance?'” the Bravolebrity said.

“A lightning bolt [is] not, like, a heart or a butterfly,” she continued. “It’s not like it’s cute.”

Maloney noted that because she was looking on from “the cheap seats,” she “could see everything that was happening.”

She explained that Madix, 37, did not notice Sandoval’s betrayal — until finding an explicit video of Leviss on his phone in March — because of how “close” she was to the situation.

Maloney — who called Leviss a “thick-skulled” and “soulless” person with “poor judgment” and “no shame” later in the interview — is not the first “Pump Rules” star to look back at red flags.

Last month, Scheana Shay spoke about Leviss suspiciously turning off her location on her phone, while Lala Kent called the former pageant queen’s Sandoval-inspired bedroom galaxy lights “a dead giveaway.”

The cast members were able to confront Leviss and Sandoval during an “aggressive” reunion taping on March 23.

While Leviss refused to define their relationship to a paparazzo last month, the pair recently dined together in Hollywood.

Leviss was also spotted at the home Sandoval still shares with Madix, and the cover band frontman drove her to the airport over the weekend.
