This shoot was set up with great lighting, everything positioned so when Will.i.am could "steal away" from the nearby recording studio, we could be finished in maybe 30 minutes. Over two hours later, we were still waiting for that to happen. Of course, the lighting had all changed but we just had to deal with that. The best part was that Will.i.am was great both in front of the camera (probably did this once or twice before) and very nice when the camera wasn't pointed at him. He definitely helped us recover from getting a late start on the day.
