“90210” star Shannen Doherty married her boyfriend of three years, Kurt Iswarienko in Malibu on Saturday. 150 people attended the black-tie bash at a private mansion. Sources tell us Doherty was walked down the aisle, over a swimming pool, by her mom as cameras rolled for the couple’s WEtv reality show. One told us, “She really did look beautiful. She wore three Monique Lhullier dresses, one with feathers, another was light pink.” Guests all wore black.
