Ahead of her early 30th birthday this week, Britney Spears has recently dethroned Google CEO Larry Page as Google+'s most-followed person.

Roughly 775,000 people follow the pop star's Google+ account. In comparison, 15.4 million fans "Like" her Facebook page and 11.4 million followers monitor her Twitter activity.

Google+ was once dominated by techies and the usual early adopters but has been attracting big-name celebrities and brands, who regularly post and incite heavy engagement. Three of the top five most-circled users, for example, are Spears, Snoop Dogg and Tyra Banks, according to Social Statistics.







Rounding out the top five is Facebook CEO Mark Zuckerberg, who doesn't have any public posts

The pattern of music makers accumulating large fan bases on social networks appears to steadily be spilling over into Google+. Twitter users helped Lady Gaga, Justin Bieber and Spears secure the most followers on the popular microblogging site. Musicians on Facebook have experienced similar growth on their fan pages and recently on their personal pages thanks to Facebook's Subscribe button.

BritneySpears.com features a gigantic Google+ icon, which likely contributed to her building the service's biggest following. Google unveiled Google+ as an invite-only beta social network in June, eventually opened it to the masses in September and now has north of 40 million users.
