Here are a few supercute pics of daddy Brad Pitt and eldest son Maddox Jolie-Pitt enjoying a lovely afternoon at the go kart track this past Tuesday in celebration of Mad‘s 7th birthday (OMG, seriously, can you believe that kid is 7 years old already?!). While the world is enamored of the new Brangelina twins Vivienne and Knox, Brad spirited his son away for a fun day of karting … behold:

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 … As the guys sped around the track, the rest of the Jolie-Pitts, including mother Angelina Jolie (whose 2002 adoption of Maddox from Cambodia helped launch the celebrated clan), remained at the family’s home, Chateau Miraval.

For more pics of Brad and Maddox‘s Birthday Race head on over to the Bauer-Griffin blog HERE. Man, I still can’t get over the fact that Maddox is already 7 years old … and still a cutie. I love pics like these … you can tell that Brad is so mindful of making his children feel appreciated. I bet Mad really enjoyed his birthday, just his dad and him paling around at the race track … it looks like it was a fun day. Happy Birthday, Maddox.
