The 57-year-old reality star told PEOPLE, 'I wasn't surprised that he cheated because we're talking about Jax Taylor - but I was surprised that he admitted it.'
Jax was reportedly cheating on girlfriend and co-star Brittany Cartwright.
Taylor, 38, revealed that he’d cheated on Cartwright, 28, with fellow Sur employee Faith Stowers on the Dec. 11 episode of Vanderpump Rules.
Vanderpump explained to the publication, 'The second episode, that was so early on in the season, I thought we’d go through the whole season with him in kind of staunch denial, but no, not so much. He had a little bit of mea culpa. Maybe he’s growing up after all.'
Vanderpump then proceeded to give Taylor some advice.
'Yes. Don’t drop your trousers at every opportunity, but that’s the advice you should give to every man, really. Isn’t it? But I know he’s growing up because he’s admitting it. However, I know he’s really grown up when he stops doing it — so we’re halfway there.'
