This is EVERYTHING we thought it would be and more!
Why? Uh, because it involves A LOT of her badonkadonk!

Ch-ch-check out the A$$-tastic video (above)!!!
O.M.G. What is on Justin Bieber's face?!
It's become clear over the past couple years that the young star wants to man up and leave his teen idol days behind.
And now that he's twenty years old, he's ready for that classic rite of passage into manhood: his first bad mustache!
It's OK, Justin! Just shave it a couple times, and it'll grow in nice and full! You'll have a full-on Tom Selleck soup strainer in no time!
Ch-ch-check out the pics (below) to see more of the Biebs' starter 'stache!
