Some 10 months after taking the Twitter title away from Lady Gaga, Justin Bieber is no longer the most followed personality on the micro-blogging site.

As of 4:45 p.m. EDT on Nov. 4, pop star Katy Perry's handle has 46,555,829 followers while Bieber counts 46,522,934.
According to Mediabistro's All Twitter news blog, Perry will likely be the first personality to reach 50 million. Of course, how many of those followers are real or legitimately engaged is a subject of some debate as many celebrities' handles count fake or bot accounts among their many millions of followers.

One thing we do know, according to All Twitter's Shea Bennett, is that, "If history has taught us anything about number one placement on Twitter, it's that once you've been leap-frogged by another user you never get it back again."
Rounding out the Top 5 of the most followed accounts, according to the websitetwittercounter.com, are Lady Gaga, Barack Obama and Taylor Swift in spots three, four and five, respectively
