The “small, spiritual ceremony” took place in Tel Aviv, Israel, where the couple met in 2010. The Don’t Trust the B—- in Apartment 23 alum opened up to PEOPLE this past August about his life as a father of four — including his household’s favorite holiday. “I’ve got kids who love Halloween so much they celebrate it throughout the year,” he said. “My son, a month ago was like, ‘Daddy, fog machine, please?’ So we got out the fog machine, we got out the Halloween decorations, they wanted it spooky so we had spider webs up, they just love Halloween.” Matt Winkelmeyer/Getty James Van Der Beek and family For more coverage, follow our babies magazine on Flipboard. Van Der Beek further explained that becoming a father changed his perspective on the work he chooses to do. “The second I had kids, they immediately became my priority and everything I did existed to support the life that was all about them in a good way,” he said. “What’s been fun about the work that I’ve been doing is that it’s so playful and kids bring out that playful side of you, so I think that’s gone hand in hand.”
