In another nod to his past, Justin Bieber posted an Instagram shot of himself in the present day alongside a childhood photo. He appears to be channeling his inner Macaulay Culkin in 'Home Alone' in the black and white shot.
The Biebs' explanation of the shot? "Haven't changed one bit." We beg to differ!

Bieber's hair and style have improved quite a bit since he was a tot, though his eyes and expression remain pretty consistent. An adorable tyke makes for a handsome young man!

We just wonder what has him so shocked. Did he finally sit down to count his cash? Did Mariah Yeater summon him to a 'Maury' stage? It's a mystery of modern man, er, tween.
