Happy 17th Birthday, Justin Bieber!

Baby, Baby, Baby.. no longer!

Justin Bieber celebrates his 17th birthday today and the mega-star has a lot to be happy about.

On tap right now for Biebs is a hit movie, "Justin Bieber: Never Say Never," a booming singing career and a hot older woman by his side - not to shabby.

It's hard to believe just a few years ago this young prodigy was just another kid trying to make it big.

Today, big isn't the right word to describe Bieber's status. Something more fitting might be epic or colossal.

So how will the larger-than-life teen ring in his new year you might ask?

Bieber recently shared his plans with Entertainment Tonight telling the outlet, "I only have, like, four days, so I'm just going to relax, because I start my world tour starting on [March 4] -- so just going to mentally prepare and just relax."

He added, "No birthday bash. ... Hopefully my grandparents will be out here, and I'll be able to spend time, a little bit, with them."

We already know how he spent some of that down time. Just days ago Bieber was photographed holding hands with hot new girlfriend Selena Gomez. The two spent the night in the $6000/night Presidential Suite at California's St. Regis Monarch Beach hotel.

Talk about California dreamin' - this kid sure knows how to treat himself.

Happy Birthday Justin!
