Bertinelli, 50, and Tom Vitale, a financial planner, tied the knot at their Malibu home in front of friends and family, including the Hot in Cleveland star's 19-year-old son Wolfgang, from her previous marriage to Eddie Van Halen.
"We're so happy," the couple told the magazine.
The pair has been together since 2004. Vitale proposed last year while on a trip to Italy. "We're both still a little afraid of commitment, but then we were over there, and it was like our souls were calibrated," Vitale said.
Bertinelli is best known for her role on the TV shows One Day at a Time and Touched by an Angel. She currently stars opposite Betty White, Jane Leeves and Wendie Malick in Hot in Cleveland, which returns for Season 2 on Wednesday, Jan. 19 at 10/9c on TV Land.
