The Monster-in-Law star proposed to Skaar in March last year (10), 12 months after the pair first met while shopping in a supermarket in Los Angeles.
At the sun-soaked ceremony at The Resort in Newport Beach, Vartan's Alias co-star Victor Garber took on groomsman duties and the couple read out its self-penned vows.
A party followed, with Icelandic band Sigur Ros playing for friends and family, according to People.com.
And Vartan reveals now the big day is out of the way, the couple is under pressure to have children: "My family was thrilled. They love Lauren and could not be happier. Now all my mother talks about is grandchildren."
