Lisa Vanderpump isn’t shocked that Jax Taylor cheated … again.

“I wasn’t surprised that he cheated because we’re talking about Jax Taylor — but I was surprised that he admitted it,” the reality star, 57, tells PEOPLE of Vanderpump Rules‘ Taylor, who has repeatedly cheated on girlfriend (and costar) Brittany Cartwright.

“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,” says Vanderpump, who celebrated the Season 8 premiere of her other Bravo reality series, The Real Housewives of Beverly Hills, on Friday at Doheny Room in West Hollywood, California.

When asked if she had any advice for Taylor, Vanderpump did not mince her words.

“Yes. Don’t drop your trousers at every opportunity, but that’s the advice you should give to every man, really. Isn’t it?” she said. “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.”

Vanderpump Rules airs Mondays (at 9 p.m. ET) on Bravo.
