How is it that teen heartthrobs get younger every day? It can't possibly be that I'm getting older, can it? I mean Kirk Cameron's still on the cover of Tiger Beat, right?

In this teaser video for Justin Bieber's new song "Boyfriend" he gets lots of attention from the ladies even though he looks not old enough to drive.

My girl is three - so, not quite to the hanging posters of cute boys on her wall stage - but I wonder who will end up taped to her wall (I hope horses and NASA scientists).

Who's hanging on your girls' wall? Is it Justin Bieber?
