Poor Pax!

According to a new report, Brad Pitt and Angelina Jolie's 12-year-old son suffered a broken leg during a family vacation in Phuket, Thailand last weekend. Pax — who was adopted by the A-list couple in 2007 — obtained the injury while jet-skiing and is now donning a full cast on his leg, sources told Us Weekly.

Despite Pax's unfortunate injury, the Jolie-Pitt clan — which also includes kids Maddox, 14, Zahara, 10, Shiloh, 9, and twins Knox and Vivienne, both 7 — continued their adventure-filled vacation with activities like mini-golfing, yachting and swimming in the ocean.
