Since the beginning of June, Ziering has been doing a guest-spot in Las Vegas’ Chippendales show at the Rio All-Suite Hotel and Casino, And on Sunday, he got visit from his former “Beverly Hills, 90210” co-stars Shannon Doherty, 42, and Jennie Garth, 41.

The gals tweeted about their mini-reunion — and appeared to be having a blast. And might we add, they all look pretty great. See a photo of all three here. Both Garth and Doherty posted pictures from their trip to Sin City:
