John Mayer was in full music mode as he headed into the recording studio in rainy NYC yesterday. Even the bad weather couldn't get him down as he was whistling a little tune. Maybe the new lady in his life is putting a spring in his step? Apparently he and Cameron went on yet another date at Mai House. These two certainly are sharing a lot of romantic dinners lately - we bet it's only a matter of time before he's writing songs about her wonderland and taking her on exotic vacations.
