Ch-ch-check out Obama's AH-Mazing final WHCD speech (above)!
Because Justin Bieber reportedly FLIPPED his shit during a recent photoshoot for an Elizabeth Arden fragrance in Copenhagen and SHOCKED onlookers with his boorish behavior!
"After showing up six hours late, Justin threw a temper tantrum because they wanted him to wear a bell boy hat — but he refused. This kid is quickly getting a reputation as someone that no one wants to work with. It was disgraceful."
Da Beebz ALSO supposedly made fans wait on him for over an HOUR at a recent concert because he was too involved in a ping pong game backstage with one of his dancers AND is rumored to have taken Selena out to a super fancy COMPED meal, where he didn't seem to feel the need to tip his waiter.
And we know tipping is different in every country you visit, but to leave NOTHING — especially after the meal is FREE — is downright tacky.
P.S. Did you hear about his tour bus being caught with narcotics!?!
