Justin Bieber is the latest celebrity to have his Twitter account hijacked, joining a long list of previous hacked victims from Miley Cyrus and Britney Spears to President Obama.

A hacker accessed Bieber’s Twitter account early on Wednesday, March 28 morning and began to unfollow and block some of the pop superstar’s fans. A tweet was also sent out to Bieber’s 19 million followers:

“19 million my ass. #biebermyballs,” the tweet said.

Although it was removed almost immediately, many fans discussed the hashtag in tweets and made the phrase trend on the site, Mashable reported.
