People:One is 7, and the other's 44, but together they share ... a need for speed. And that explains why, for his seventh birthday on Tuesday, Maddox Jolie-Pitt and his father, Brad Pitt, spent a guys' day out behind the wheel, pursuing one another around a go-kart track in the South of France. The two have demonstrated their love of wheels before – competing with radio-command cars, racing various bikes and visiting Formula One races. Only, this time, it was their feet on the cart pedals. "It was just Maddox and Brad," says a source. "Just father-son time." And even though Brad stripped down to don his racing leathers, according to the source, it was Maddox who crossed finish line first.
