(Cover) - EN Showbiz - Brad Pitt and Angelina Jolie have hired a river boat to celebrate their son Paxs seventh birthday.

The Hollywood couple have six kids, Maddox, nine, Zahara, five, Shiloh, four, two-year-old twins Knox and Vivienne and Pax, who is seven today.

They decided to celebrate Paxs birthday a day early, organising for him to have a party on a boat called Josephine on the Seine River in Paris last night. Maddox, Zahara and Shiloh were all in attendance, and were excited when they saw a special cake and balloons in their brothers honour.

The family were all dressed warmly to guard against the bitter weather, with Angelina opting for a chic camel coat and Brad a black one with matching hat. While she spent time pointing out impressive buildings to the kids, Brad stood back and filmed the family.

On Saturday, the couple took Shiloh and Zahara shopping in the city. The group picked up a number of gifts and clothes, with the Hollywood stars stunning onlookers with how normal they were.

Angelina was great, a source said. She's patient, and a very hands-on mother, making certain everything fits.

Among the items the group went home with were trousers, pyjamas, stuffed animals, a Duchess dress for Zahara and a medieval knights outfit, with sword and shield, for Shiloh. The little girl picked up two versions of the costume, telling store staff one was for Pax. She later grabbed a plastic alligator, and revealed: That's good for Knox. (C) Cover Media
