The Six-pack at the Center of a 90210 Reunion

Ian Ziering’s six-pack is so hot – how hot is it? – it brings the girls to the yard.

Well, to Vegas, actually.

The actor and his rippedlicious 49-year-old bod welcomed his Beverly Hills, 90210 co-stars Shannen Doherty and Jennie Garth to Sin City over the weekend. The pair arrived in town to check out how Ziering shakes it on stage while performing with the Chippendales guys.

Nice...and nice, huh.
