The Jonas Brothers, Nick, Kevin & Joe are pretty busy these days.  Here they are filming an as yet untitled 3-D movie in downtown L.A.  According to the photo write up, Nick, the youngest, appears tired and yawned most of the day.  This was probably from late night partying last night, as he rented out Dodgers Stadium to celebrate his 16th birthday yesterday (which was actually on Tuesday).

You know you’ve hit it big when you have to have security escort you to a port-o-potty!!

Lots of pics after the jump
