ET got some of the biggest stars in Hollywood to dish on their favorite holiday traditions.
Joy star Bradley Cooper and his family are all about the food. "I grew up in an Italian family and half Irish, but we cook," he told ET. "You only have seafood on Christmas Eve, so it's big. We just eat basically. Just cook and eat. It's an excuse to just keep eating."
The Hateful Eight star Channing Tatum and wife Jenna Dewan-Tatum use the holiday as an excuse for excessive coordination. "We do onesies every year," Tatum said. "We get the two dogs -- they get onesies. The baby, Jen and I, we're all in the same onesies. I realize I love a onesie. Onesies are dope! But you need the pocket ones. That's, like, the big mistake if you don't get the pocket version of the onesie. You're kicking yourself all day."
Bindi Irwin and her family will be happy in their element. "This year for Christmas we're going to go out to one of our conservation properties out near St. George, so it will be beautiful," said the Dancing With the Stars champ. "We will be hours from the nearest town and we will be with kangaroos and emus and all kinds of birds, so we will be out snake-catching every night and watching the sun rises every morning! It will be perfect."
Golden Globe winner Steve Carell and his crew will be having the most traditional celebration, as long as our interview didn't ruin anything. "My kids are all a little older now, but my son still pretends that Santa exists," the funnyman said. "I hope he's not watching this."
