TORI SPELLING

Despite a long-lasting career, Spelling – who made several appearances as Screech's nerdy girlfriend Violet – considers her family with husband Dean McDermott her greatest accomplishment. The actress-turned reality star welcomed her fourth child, son Finn, in August, the latest addition to her brood which includes almost-1-year-old Hattie (pictured in December 2011), 4-year-old Stella and 5-year-old Liam. "We feel truly blessed that another little angel has found us," she said.
