Actor Edward Burns loves spending time with his in-laws over the holidays - because his brother is married to his supermodel wife Christy Turlington's sister.

The Saving Private Ryan star wed Turlington in 2003 and a short time later his scriptwriter brother, Brian Burns, tied the knot with the beauty's sibling Kelly.

Planning family gatherings has never been easier, and Burns reveals each year they get together to open presents and take pictures, all while wearing matching pyjamas.

He says, "That's something Christy's family had been doing for years that we now have adopted as well. My brother married Christy's sister and all of their kids (do it). And then Christy's sister in California (does it) as well... (with her) three kids - so that's a lot of Pj's. It makes for some very fun photographs. Fortunately I'm not in charge of (picking them out)."
