EXCLUSIVE: Ben Stiller Reveals Secret to His 15-Year Marriage as His Son Gives Blue Steel Stares

Ben Stiller has a little Derek Zoolander on his hands!
The 50-year-old actor's family joined him at the New York City premiere of Zoolander 2 on Tuesday night, and his 10-year-old look-alike son, Quinlin Dempsey Stiller, that stole the limelight.

Quinlin did his best Blue Steel stare as he posed for pics on the purple carpet with his dad, mother Christine Taylor and his 13-year-old sister Ella Stiller.
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."
We certainly see the sense of humor in this family! Zoolander 2 hits theaters Friday, Feb. 12.
