Johnny Depp kept a protective hand on his son Jack's back during a shopping trip at Ralph Lauren in Europe today. It's rare to see Johnny's kids out and about, but the 8-year-old is a frequent visitor on dad's movie sets around the world. Johnny has been trekking through the continent this week on a press tour with Angelina Jolie for The Tourist. Their last stop was in Madrid yesterday, and now the costars have gone their separate ways with Johnny seeing his family and Angelina taking care of her latest humanitarian mission. The duo will reunite for more promotion, and perhaps they'll make appearances on the Golden Globes red carpet since they're both nominated for their work together. Johnny also scored a nod for Alice in Wonderland, which was a bit less surprising. This week we also got a glimpse of Johnny's next two big-screen releases with the first trailers for both Pirates of the Caribbean: On Stranger Tides and the animated Rango.
