FIRST PHOTOS - Brad Pitt, Angelina Jolie and Family Celebrate Pax's Birthday In Paris!

Brad Pitt and Angelina Jolie chartered a bateau mouche for a private family dinner on the River Seine last night in Paris to celebrate son Pax's 7th birthday -- oh la la!

Most kids don't celebrate their birthdays with a private cruise around a European capital with photographers snapping away as their famous parents down red wine (see the gallery pix of Brad tipping back a few) ... but such is the life of Pax Jolie-Pitt. The first-grader was surrounded by his family, with Maddox, Zahara and Shiloh all in attendance while the younger twins -- Vivienne and Knox -- stayed home.

It appears Angelina has wrapped filming on her Bosnian war love story directorial debut after leaving Budapest a week ago, stopping over in the Seychelles for some R&R, and then heading to Paris with the family.

What's next for these globetrotters?!
