Forget The Gosselin Kids -- Why Isn't Anyone Worried Justin Bieber Will Burnout?

Aug 19, 2010 | Updated May 25, 2011

He's 16, and he barely has had a day of downtime since hitting it big. Is it legal or moral for a kid to work this much? Is he the next Michael Jackson?

Does Justin Bieber secretly have a twin? Or a clone?

He must -- he's EVERYWHERE! The 16-year-old singing phenomenon has done 46 concert appearances in the U.S. and Canada alone since last Dec. 23, and he's sung on the Today Show, The View, Jay Leno, Jimmy Kimmel and George Lopez. He's even become the "it" fashion accessory of the season.

Elle magazine photographed him in the Bahamas as 29-year-old Kim Kardashian's boy toy for their September issue, and then Glamour shot him with a blonde model towering over his 5'4" form in a six-page fashion spread the same month.

Listen -- those shoots alone took at least a day each plus travel time. And he somehow found time on top of that to squeeze in shooting videos with Ludacris, Sean Kingston and Jaden Smith to promote his latest hit record My World 2.0.

The kid has traveled from the UK to Australia to Japan for concerts in the past year, and he has been mobbed from one corner of the world to another.

Now he's just tweeted his excitement about another upcoming gig -- "performing at this years VMA's!!! Last year I went and no one knew who I was and this year gonna PERFORM!!! Wild!! DREAM BIG!"

But before he gets there, he's set for an Aug. 31 show at Madison Square Garden -- "gonna be INSANE!!! Everyone come fill the streets! We are gonna try and make history!!!

Are you getting tired just reading about the Bieber bombers' punishing schedule? How do you think he feels?
