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?
