The "Hot in Cleveland" star and Vitale were married in a small ceremony at their Malibu home, People magazine reported Sunday.
"We are so happy," Bertinelli said.
About 100 guests, including Bertinelli's 19-year-old son, Wolfie, witnessed the marriage Saturday.
Bertinelli, 50, met her 49-year-old financial-planner husband in 2004 and became engaged last March during a vacation in Italy, People said.
