Canadian pop/R&B singer, songwriter, and actor Justin Bieber had his Twitter account allegedly hacked today. Whoever did it decided to question his follower count and insult him with a popularly-used phrase amongst those who dislike him.
It was potentially seen by Bieber’s 19 million followers, or even more, given that Twitter is a mainly public social network. The remark was aimed at the fact that Bieber today crossed the 19 million follower milestone. The tweet was subsequently deleted. Either the hacker in question deleted it right after posting it, or (more likely) someone else was active on the account at the time, saw it, and deleted it.
