Justin Bieber is celebrating big today. Why, you ask? The "Sorry" singer is turning the big 2-3 today. Doesn't it feel just like yesterday when Bieber was a little swoopy-haired tween? We think so, which is why we're honoring his birthday by taking a walk down memory lane.
Whether they were good pals or just posing together at a event of some sort, Justin used to hang with a lot of people that you'd never catch him spending time with nowadays. From attending award shows with his former girlfriend Selena Gomez to performing with stars like Jordin Sparks these Biebs encounters are not likely to happen today.
