Is Justin mad at president Obama?

When the president accidentally introduced him as Justin "Bye-ber" at a White House event, Justin just laughed. As he told People, "He messed up my name, but I give it to him. He's not [the] age category I sing to. He's not 'One Less Lonely Girl." But Justin was a little upset with People thanks to the pic they used of him on their cover! He tweeted, "next time I laugh real crazy warn me you are still taking pics... still appreciate you but let's get on the same page." He later deleted that tweet but added " I look crazy as heck on the cover but if you can't laugh at yourself you ain't having fun."
