Brad Pitt to Pax Rock-a-Bye Baby

Brad Pitt further proved he's the coolest dad ever by taking sons Pax and Maddox to a Green Day concert in New Orleans last week.

While it may or may not be a testament to the band's music, Brad made sure the boys' ears were safely covered and plugged.

Apparently, all that punk/pop screeching was enough to rock Pax to sleep.
