Justin Bieber has unquestionably achieved a lot in his short career. And with two multi-platinum selling records, an AMA for Artist of the Year, and multiple Teen Choice awards, he's just short of world domination, and a few other things. In honor of the 'Baby' singer's 17th birthday, here's a playful list of 17 things Justin Bieber has yet to accomplish.

17. Grow a beard. We've never seen so much as a speck of dirt on Bieber's face (and no, the Best Buy commercial does not count), so we're not even sure if he could pump out the facial hair if he tried. The 17 year old is as 'Baby'-faced as they come, but that's okay -- we like him that way!

16. Duet with Taylor Swift. He's laid down tracks with Miley, Kanye, Usher and the Rascal Flatts, but so far JB has yet to team up with Taylor Swift. We know he's a fan (he dedicated 'Favorite Girl' to her in 2009). If the two pop icons should join forces, it would inevitably be a monster match-up.

15. Outwardly date a fellow celeb. Speaking of Taylor Swift ... Just kidding! Justin probably wants to keep his name clean -- so no 'Dear Justin' dedication for him. But we do think there's something the 'Baby' superstar is keeping a secret -- and it rhymes with Welena Momez.

14. Release a 'Greatest Hits' record. 'My World,' 'My World 2.0,' 'Justin Bieber's Greatest Hits?' Honestly, it's only a matter of time.

13. Buy a house. At 17, Justin Bieber is well on his way to becoming a man. Now, the next step is to move out of mom's house and purchase a sweet bachelor pad! Can you say party central?

12. Join the NBA. After being named MVP at the NBA All-Star celebrity basketball game, going pro is the most logical next step.

11. Start a rock band. Justin can play the drums like nobody's business, and dance himself into a frenzy -- but we've yet to see him rock a stadium as a one-man band.

10. Come out with a clothing line. He's already got his own set of nail polishes, but aside from pretty fingers, the Biebs has yet to share his eye for style with the world. Picture a place where boys and girls alike don striped hoodies, purple caps and Supra footwear -- that's where we want to live!

9. Have a baby Bieber. Ok, we're sort of kidding. Justin's mom, Pattie, is probably thrilled that he's not quite ready to produce a kid of his own. But we're just really curious to see if baby Biebs would come out already donning his dad's signature swoop hairstyle.

8. Appear on 'Glee.' Bieber has appeared on CSI and even has his very own movie -- but despite his music being the center focus of an episode of the hit FOX show, the 'Never Say Never' star has yet to make an appearance on 'Glee.' At 17, we think he'd fit in perfectly as an exchange student ... From Canada.

7. Record a rap album. At least, as far as we know. He's had a hand in mixing thanks to Kanye. Could 'Dr. Bieber' be the beginning of a full-length compilation of rap masterpieces?

6. Star in a movie with Johnny Depp. We know the 'Pirates of the Carribean' actor is a Belieber. We could definitely see them dueling on the beaches, or perhaps starring in an animated feature?

5. Start his own music label. Might we suggest Belieber Productions?

4. Graduate high school. If Bieber were a typical teen, he'd be entering his senior year of high school this fall. But even though he's home-schooled (he's on the road 24/7), Justin should snag his diploma soon!

3. Drink Legally. He's Canadian, which means Bieber still can't hit the bottle legally for another two years -- and four years in the US! Let's hope no one spikes the punch bowl at all of the award show after-parties he attends.

2. Release a movie in 4D. A 3D movie? Get with the times! When Justin goes 4D, we'll be first in line. Hey, never say never!

1. Win a Grammy. Ouch! Sorry Bieber, 2011 just wasn't your year. But it's great just to be nominated, right?
