The couple took the youngster and three of his siblings – Maddox, nine, Zahara, five, and four-year-old Shiloh – on the French city’s River Seine yesterday evening (28.11.10) in a chartered boat named Josephine.
Birthday boy Pax was treated to a special cake while the boat was decorated with balloons.
Despite the cold weather Pax, Maddox, Zahara and Shiloh all seemed to have a great time although there was no sign of their two-year-old twin siblings Knox and Vivienne.
As well as celebrating Pax’s birthday, earlier in the day Brad and Angelina had taken Zahara and Shiloh Christmas shopping in the French capital.
The little girls were seen trying on clothes at the Bonpoint boutique, with Shiloh picking out trousers and a pair of zebra-patterned boots while Zahara chose black suede boots and a dress.
Shiloh – who is known for her tomboy style – also picked out two sets of medieval knight's tunics for her and Pax, and also chose a large plastic alligator for Knox.
A fellow shopper at the store told People magazine: “Angelina was great. She's patient, and a very hands-on mother, making certain everything fits.
“Brad was very agreeable, absolutely polite and excellent with the girls.”
