Pine away for your banner years.
As of a week ago. Time flies. It seems like he was just 14 not too long ago.
Justin Bieber is ringing in his big 2-0.
While the Biebs has kept mum on how he's celebrating the end of his teenage years, he did retweet several birthday wishes from friends and celeb pals including Carly Rae Jepsen, his manager Scooter Braun, his parents and his Shots app business partner Johnny Shahidi.
"Love you my little bro.. happy birthday," Shahidi wrote, posting a shot of the "Boyfriend" crooner blowing out a cake that read "Happy Birthday Bizzle"
His rumored ladylove Chantel Jeffries also posted (and then deleted) a birthday tribute on Instagram, writing "Joyeux anniversaire," or "Happy Birthday" in French.
In the snap, the duo is posing together in a backyard, but it's not clear if the shot was actually taken today.
