Selena Gomez has knocked boyfriend Justin Bieber off the top of Billboard's new Social 50 chart.
The countdown ranks the most active artists on the world's leading social networking websites YouTube, Vevo, Facebook, Twitter, MySpace and iLike.
Buzz surrounding the release of her third album, "When the Sun Goes Down," and new movie Monte Carlo helped give Gomez the edge over Bieber.
She also posted a much-publicized video of her embarrassing first meeting with crush Shia LaBeouf on YouTube.com.
