Lada Gaga has been displaced as the most followed person on Twitter, according to a report by E! Online. The new No. 1 is another pop star: Justin Bieber.

The piece notes that Bieber recently mooned his followers in an Instagram photo, which the report hints may have helped boost his online popularity.

The website reported today: “As of last count this morning, the 18-year-old superstar had a whopping 33,333,554 Beliebers (and counting) to Gaga’s still whopping but now slightly less so 33,328,937 Little Monsters.

“Neither star has yet acknowledged this momentous milestone.”

Gaga remains No. 1 on Facebook, the report notes, with 54.98 million likes to 50.66 million for Bieber.

“But that’s not the only online overtaking Bieber may have up his sleeve,” the piece adds. “His Instagram followers currently top out around 6.1 million, not too far off from the reigning queen, Kim Kardashian, who has 6.3 million followers on the photo-sharing site.”
