Justin Bieber is growing up fast.

The Canadian singer-performer turned 23 years old on Wednesday, March 1, and following Camila Cabello's tweet playfully wishing for "bigger boobs" for her 20th on Friday, he used Instagram to share his birthday wish with his followers.

"It's my birthday and all I want is to be a better friend, better brother, better son and and better man," the pop star wrote in the caption of a childhood photo of himself, which has since received over 260,000 birthday well-wishes.

In addition to getting philosophical, Bieber also "got some air" on Thursday when he took his ATV out for a ride on some sand dunes.
