Jax Taylor nervously called fiancée Brittany Cartwright to confess that women were in his hotel room on Monday's Vanderpump Rules.
Plans for the boys' night at the Mondrian hotel while the women went away to wine-tasting mecca Solvang had already caused friction between them.
'Don't disappoint me,' Brittany had begged Jax, 39, of the party plans, begging him not to bring back 'those old feelings' when he cheated.

'I should probably cancel the strippers that I hired then,' he joked.
He later snapped at her when she chased him up to see if he was there, with him telling her: 'I already have one mother, I don't need another one.'
'You sound like a d**k,' Brittany replied, insisting she has a 'right' to know where he is considering his previous cheating.
