Ben and Christine -- who appeared in the first Zoolander together and are now co-starring in the sequel -- told ET that the secret to their 15-year marriage is "having a sense of humor."
"I think you got to laugh. Because you know after a while you know life is life you know?" Ben said. "We all have to deal with what life throws at us, so you got to have a sense of humor about it. If you can share that, at the end, it makes a huge difference."
