Justin Bieber's breakout music video for hit single 'Baby' has hit ONE BILLION plays, making it the most watched Vevo clip ever.
The 19-year-old's fans were quick to celebrate the milestone, getting the hashtag #BabyHit1Billion trending on Twitter.
The news was announced by the YouTube music video provider, who tweeted: ".@justinbieber's "Baby" music video has reached 1 BILLION views on @vevo, our most watched clip ever http://vevo.ly/hW8OXO #BabyBillionVEVO"
However, the troubled young popstar still has a little way to go if he is to knock Psy's 'Gangnam Style' from the top spot as the most-watched music video on YouTube ever.
Psy's clip, featuring that famous horsey dance, is fast approaching the 2 billion view mark.
