Since Bieber made the song famous, One Less Lonely Girl has become the slogan for many Beliebers, with Justin traditionally performing the song at his gigs with a fan from the crowd who he serenades and gives a red rose.
In other JB news, his hit single Baby has surpassed over 500,000,000 million views on YouTube.
