The 40-year-old actress exchanged vows with artist Davey in an intimate ceremony at Paramour Mansion with around 60 guests of close friends and family on Saturday (12 October).
An excited Rose, who played Paige Matthews in the supernatural drama, told her Twitter followers yesterday: "Hell to the yeah! I'm a Mrs.! What?! AWESOME! Love to you all!!!!!"
Rose wore a white dress and veil for her big day and guests were later treated to a New Orleans swing band, Us Weekly reports.
Rose and Davey, who got engaged in July, have been dating for just over a year and are reportedly planning to travel to Tahiti for their honeymoon.
