Brad Pitt stepped outside for a smoke break while running errands in Paris this afternoon. He talked about kicking his bad habit because of his kids last year, but it looks like he's picked up his old vice again. Brad arrived in France with Angelina Jolie and their children over the weekend, just in time to celebrate Pax's seventh birthday with a hot-air balloon trip and a boat ride on the Seine. Shiloh and Zahara were apparently also treated to a day of shopping, like they did during another visit to the city earlier this year. Their six young ones stayed behind, though, as Brad and Angelina worked the red carpet in matching black for the premiere of Megamind this evening. It's a big week of work for both Brad and Angelina, as she'll be busy promoting The Tourist over the next few days ahead of its Dec. 10 release.
