Las Vegas is 300 miles from Beverly Hills, but that didn't stop a mini "90210" reunion from happening in Sin City.

Original "Beverly Hills 90210" castmembers Shannen Doherty and Jennie Garth attended costar Ian Ziering's Chippendales show at the Rio All-Suite Hotel and Casino on Sunday.

"Chippendales is a very interactive show and we managed to surprise them both by including them on stage in a few production numbers," Ian told People. "I was very flattered by their comments. And judging by their reaction, I know they had a great time."

Sounds like the 49-year-old and his toned troupe put the strip in Strip. A smiling Jennie wrote in an Instagram pic, "I don't know what to say," surrounded by the shirtless studs.
