“Mystery Girls” co-stars and former “Beverly Hills, 90210” BFFs Jennie Garth and Tori Spelling stopped by the “Watch What Happens Live” clubhouse on Sunday (June 29) where they spilled some fun secrets about “90210.”

Watch above for a rapid-fire round of questions about the former teen soap. When asked who was the better kisser, Luke Perry or Jason Priestley, Jennie Garth says Priestley. She also says Priestley partied harder than Shannen Doherty, and both Jennie and Tori agree that Tiffani Amber Thiessen was the late-comer who fit in best with the cast.

Below, watch as the girls talk about who they’re still in touch with, Tori denies that she sold Priestley’s wedding invitation at a garage sale (“It would have gone for a lot more than five dollars”) and they reenact a Season 2 scene with host Andy Cohen playing the part of Brenda Walsh, when she’s worried that she’s pregnant.

“Mystery Girls” airs Wednesdays at 8:30 p.m. ET/PT on ABC Family.
