Childless Clooney feels left out

George Clooney feels left out on the set of Ocean's Thirteen because castmates and pals Brad Pitt and Matt Damon are bonding over their new babies.

Damon's wife Luciana Barroso gave birth to their first child together, daughter Isabella, in June, just weeks after Angelina Jolie delivered her and Pitt's baby Shiloh Nouvel in Namibia.
