Justin Bieber Followers Challenge Lady Gaga Fans to Twitter War

It is on between the Beliebers and the Little Monsters.

After Lady Gaga usurped Justin Bieber's throne on Twitter this month, taking over as the most-followed person on that social networking service, a fan of the teenage sensation took to the Internet and - as excerpted by The New York Post - wrote:

"To all beliebers this is operation unfollow Lady Gaga. I'm sorry if your a 'little monster' but don't [you] want Justin to be #1 followed on Twitter?"

As a result of this campaign, the hastag #OperationUnfollowGaga has sprung up on Twitter.

Naturally, Lady Gaga's followers aren't on board with this plan. One Tweeted it to be "pathetic."

And what are the current standings? Bieber - who released a new single this week - checks in at 19,115,097 million followers. Lady Gaga has him beat at 21,813,419.

It's now time for you to take a side. What are you, readers?
