Poor Katie Holmes, Tom Cruise might as well put her on a leash! Everytime you see them together he's holding on to her so she won't get away. Look at her expression, it's a cry for help! Well, seems they had a little public drama:

"Tom and Katie began arguing loudly and in front of everyone," continues our super source, who was inside the basketball game. "[Cruise's son] Connor was looking on uncomfortably until Tom's sister and publicist, Leanne, stepped in to arbitrate."

After their fight, Tom & Katie made a quick exit out the back and didn't stay for the rest of Isabella's basketball game.

Poor kid too, is it possible that any Hollywood kids will turn out normal? No, I didn't think so either!
