'Baby'
Just look at this. You'll forgive us for referring to Justin Bieber as always being a 12-year-old with a mop top.
Selena Gomez
Now this is sure to make you laugh. Bieber and Selena started began dating after the two met with their managers. Here's the squirm-inducing first tweet that Bieber sent to Gomez, where he said "good seeing u. Until next time. Maybe new years ;)".
@selenagomez good seeing u. Until next time. Maybe new years ;)

The couple then began dating around the time 'Baby' was released in January of 2010. What followed was a series of ups and downs that fans were furiously following at every moment. The couple eventually called in a day in 2012 - although they appeared to be on and off for a while after this.

'Boyfriend'
Justin Bieber released 'Boyfriend' in March 2012, which was a departure from his previous squeaky-clean image.
Calvin Klein
Remember when it was announced Bieber would be the new face of Calvin Klein?
And the inevitable 'Saturday Night Live' skit that followed, with Kate McKinnon as a very convincing Bieber.
Fashion Rocks
There was also that time he got down to his underwear to a chorus of boo's...
"I did things that I'm not proud of"
It seems "pretty boy" Bieber caused some controversy a number of times over the years. A couple of years back he get into a fight with a man twice his size; he was also caught smoking marijuana; accused of hitting his limousine driver in the head; charged with vandalism for egging a neighbour's house; and even arrested for being under the influence while drag racing. He apologised to his fans on 'The Ellen Show'.
This day 4 years ago my baby @justinbieber got arrested. I'm so proud of him cuz he could go through it. He is a better person 100% now and that's all what matters. God bless U, U are a good person,friend,son and a future father ❤ #Beliebersstayforever #BestFanArmy #Beliebers pic.twitter.com/Aa1yTCFn72

'Sorry'
Bieber made us forget about all of his previous pitfalls when he released the singles from his album 'Purpose' in 2015. The singer seemed to drop banger after banger, from 'Where are you now?' to 'What do you mean?'. The music video for his single 'Sorry' alone, has over three billion views.
Carpool Karaoke
You know you're made it when you're singing in a car with James Corden.
'Despacito'
Last year you couldn't move without hearing 'Despacito' coming out of every crevasse it could worm it's way out of. A good tune at first, that rather quickly turned into a head-wrecker which spurred countless copy-cat versions to jump on its success.
Married
According to reports, Justin Bieber tied the knot with American model Hailey Rhode Baldwin in October this year. A fan named Nona Melkoni sat near them at a restaurant and said, "I asked them if they were married and they simultaneously said yes!"
The Canadian singer has only been in the spotlight for eight years, and he's already lived quite the life. What's your favourite JB memory? Let us know in the comments.
