"I never found myself needing that piece of paper," Depp said as to why he and Paradis haven't tied the knot. "Marriage is really from soul to soul, heart to heart. You don't need somebody to say, okay you're married... If Vanessa wanted to get hitched, why not... But the thing is, I'd be so scared of ruining her last name. She's got such a good last name."
The actor and Paradis have two children; Lily-Rose Melody, 11, and John Christopher, 8, who will all be spending the holidays at home relaxing.
"Sleeping, sleeping and playing with a lot of toys with my son," Depp revealed about his holiday plans. "Hanging out with the kiddies."
Currently co-starring with Angelina Jolie in "The Tourist," Depp said he was "pleasantly surprised" to find out how normal she is. "She's just a regular gal... with a perverse sense of humor. She's got a vivid and energetic sense of humor. She doesn't mind traveling to the dark or to the very weird."
With two of the biggest stars in Hollywood in the same movie, the paparazzi were all over them while they filmed in Venice. Says Depp, "It was like wallpaper. There were so many. I've never seen that many in my life. You'd leave your hotel to get in a boat to go to work and the question was, 'how many today?'"
