ONSCREEN: Milano is a good witch on the WB's Charmed. Krause plays her guardian angel on the show.
HOW THEY MET: The costars were already friends when Milano ended her 11-month marriage to musician Cinjun Tate in November 1999. They began dating earlier this year. "Our relationship is great — very stable and very adult in the sense that there's no drama. [Brian's] just awesome and delicious and a great man," said Milano, who grew up in Los Angeles and was briefly engaged to Party of Five star Scott Wolf from 1993 to 1994. In 2000, Krause, a native of El Toro, California, divorced model Beth Bruce, with whom he has a 5-year-old son, Jamen.
MOM'S THE WORD: Krause's wardrobe ultimately won over Milano's mother, Lin Milano, who is a fashion designer. "The first time [Brian] came over for dinner, he was wearing this beautiful suede jacket, and my mom was hanging it up, and I could just see her face," said Milano. "Little things are very important to parents."
