Canadian teenybopper/global irritant Justin Bieber has become the second Twitter user to reach the 20 million follower mark, passing the milestone late last week. Bieber joins Lady Gaga as the only other member of Twitter’s 20 million club, with Katy Perry likely to join them towards the end of May.

However, it’s not all sunshine and glory at the top-end of Twitter’s most-followed list – following an altercation with a user, hip hop star Nicki Minaj has deleted her Twitter account… and with it her 11 million fans.

Minaj became upset when the @NickiDaily profile (now removed, along with their website) started posting snippets from her new album on Twitter. After initially ranting in a series of tweets, Minaj then deleted her profile.

Of course, few things in this crazy world of social media are forever. Minaj has 30 days to reinstate her username, and I wouldn’t be surprised to see her returning to Twitter before the month is out. And to be honest, even if she doesn’t, I’m not sure there’s all that much to mourn.

Bieber, meanwhile, registered his 20 millionth follower on Thursday, and noted the occasion with a tweet.

Shudder.

Coincidentally, Bieber also has a new album coming out. With any luck, somebody will leak that, too.
