Brad Pitt and Angelina Jolie threw a birthday party for son Pax that only they could throw -- by renting a boat on the Seine River to check out the Eiffel Tower!
Brad, Angie, Shiloh, Zahara and Maddox all loaded onto the boat in France last night for Pax, who turns 7-years-old today.
The twins, Knox and Vivienne sat this bash out and were not seen at the party.
Check out all the fun pics!
