`90210' ZIPS INTO TV HISTORY TOMORROW

BEVERLY HILLS, Calif. (Wireless Flash) -- The final episode of "Beverly Hills 90210" airs tomorrow on Fox and cast member Luke Perry should be especially nostalgic. Before Perry was cast as Dylan McKay, he was an asphalter who helped lay tar on the parking lot of the school that became the set for "90210's" West Beverly High. Other 90210 cast members with bizarre secrets include.... -- Shannen Doherty, who once demanded "90210" producers supply her with 10 bottles of Evian water to wash her hair each day. -- Tori Spelling, who admits she fantasizes about having a threesome with Nicole Kidman and Tom Cruise. -- And then there's Ian Ziering. Famous L.A. "party girl" Ursula Auburn claims she once had sex with Ziering, who screamed so loud she thought he was having a heart attack.
