Lady Gaga Close To Besting Britney Spears In Twitter Followers

Spears is the world's top tweeter, but Gaga is hot on her heels.

Lady Gaga's near-dominance of all things social media is reaching a pivotal point: Mother Monster is poised to topple Britney Spears as the most-followed Twitter user.

According to the social-media website FameCount, which tracks the most popular entities on sites such as Facebook, Twitter and YouTube, Spears is the world's top tweeter, with more than 5.6 million followers, but Gaga is right on her heels. As of Thursday afternoon (August 19), Spears' followers numbered 5,646,028, while Gaga's online army of "little monsters" was 5,635,460 strong. The ranking could switch very soon, since Gaga has netted around 600,000 new followers this month, while Spears pulled in about 200,000. The site also lists Gaga as the most popular online entity worldwide, with more than 16 million Facebook fans and 330,000 YouTube subscribers.

Gaga's pre-eminent Twitter status is just the latest milestone marking the pop phenom's powerful viral presence. Last month, Gaga soared past the leader of the free world, President Obama, in Facebook fans. The "Alejandro" singer was also the first living person to notch 10 million fans on the intensely popular social-networking website.

Despite runaway online popularity that rivals her chart-topping music sales, Gaga still has to fend off competition from other pop stars. In July, Justin Bieber bested Gaga for the most-watched music video on YouTube with more than 245,746,720 views for the Ludacris-assisted collabo "Baby." Gaga's futuristic-disco extravaganza "Bad Romance" was close behind with 245,596,709. Bieber has since widened the gap, however, with "Baby" scoring 292,285,435 views to Gaga's 264,533,336 YouTube spins at press time.

Gaga's viral presence is undeniable, but the singer's outsize fan support has yielded results in the form of cold hard cash as well. After circling the globe on her Monster Ball Tour since November of last year, the seat-filling tour is on track to gross $200 million worldwide by April 2011.
