Maddox Jolie likes hanging with Brad Pitt
as much as Angelina Jolie
does: The guys read, play on the beach, ride dirt bikes. But in Manhattan last week, the 4-year-old and his new sister, 7-month-old Zahara, were digging alone time with Mom. In town to begin filming the thriller The Good Shepherd, costarring Matt Damon
and directed by Robert De Niro, Jolie, 30, took the opportunity to take the focus off her romance with Pitt (who, a source says, was in town before heading to Canada to film The Assassination of Jesse James) and treat her kids to urban-kid pleasures from museums to movies to plenty of toy shopping. On Aug. 11 the three stopped at Lee's Art Shop, where Jolie picked out, among other things, a $13 temporary-tattoo kit for Maddox—though when he presented more toys to her, she told him, "We bought enough today."
There's always tomorrow. At Saks Fifth Avenue on Aug. 12—with shoppers looking on—Jolie picked up some Ralph Lauren clothing and took a break to give her daughter a bottle. The next day all three Jolies caught a movie at De Niro's Tribeca screening room. But it was girls only again Aug. 16, as Jolie and Zahara hit the Guggenheim Museum and the Manhattan Art and Antiques Center. Her boys? Perhaps at home picking out tattoos.
