Angelina Jolie took a break from her press duties to accompany her son Knox to the aquarium in Paris today. The 2-year-old clung onto his shark stuffed animal and marveled at the snow, which seemed equally impressive to his movie star mom. It was Knox's turn to check out the fish after Angelina brought Shiloh and Zahara there yesterday. Angelina cited Knox's twin sister Vivienne, however, as her inspiration playing a very feminine character in The Tourist. During her junket interview, Angelina joked to us that she "kind of played Vivienne" in the film, since the little one is naturally a "real girl" unlike Jolie herself. The whole family is taking advantage of their time in the city, which included a date night for Brad and Angelina, boat trip on the Seine, and hot air balloon birthday for Pax. Angelina says they spend more time at their place in the South of France than the capital and she revealed that her older kids are better than she is at speaking French, saying, "My kids are passing me, which is driving me insane. So I'm about to get back in class!"
