Absence may make the heart grow fonder, but it also can lead to suspicions of infidelity.

In the season 3 premiere of Vanderpump Rules, ridiculously good-looking bartender Tom Sandoval finds himself accused of cheating on his girlfriend Ariana Madix – and PEOPLE has the sneak peek video to prove it.

In the clip, Tom admits to his girlfriend’s pal Scheana Marie that he exchanged numbers with a girl while he was on vacation in Miami, but he denies that anything happened between the two of them.

The rumors were started by Tom’s ex-girlfriend Kristen Doute, who has started dating Tom’s former friend James, despite the fact she still has feelings for Tom.

Did we mention all these people work together at Lisa Vanderpump‘s West Hollywood restaurant SUR? Talk about a toxic work environment.

Season 3 of Vanderpump Rules will begin Monday (9 p.m. ET) on Bravo.
