Justin Bieber celebrates his 22nd birthday today (1 March 2016) and what a year it has been. The Canadian superstar stormed back onto the charts in 2015 with a whole new image, improved attitude and a fresh direction of music to unleash on the music world.

Turning 21 was more than a milestone for Bieber as he sought to leave his controversial bad boy behaviour in the past and turn over a new leaf. After a brief spell away and several public apologies, Bieber returned with a new sound that found him teaming up with EDM kings Skrillex and Diplo, also known collectively as Jack U.

Their dance single Where Are U Now became an instant hit in clubs but it was Bieber's subsequent singles that really made an impact on the charts. Sorry, What Do You Mean? and Love Yourself topped the charts around the world, including the UK and US Billboard Hot 100 charts, earning Bieber his highest positions with singles to date.

All singles featured on Bieber's critically-acclaimed fourth studio album Purpose, which trumped One Direction's Made In The A.M. to claim the number one spot in the US. Simply put, Bieber has made one heck of a comeback, so in celebration of his 22nd birthday, IBTimes UK takes a look at his past year in numbers.
