Lady Gaga's Twitter followers reach 20m mark

London, Mar 6 (ANI): Lady Gaga has become the first Twitter user to amass 20 million followers.

The singer tops the microblogging site's most popular list ahead of fellow pop stars Justin Bieber (18 million), Katy Perry (15.7 million) and Shakira (14.5 million).

Gaga's massive following is in addition to 48 million fans on Facebook and more than 800,000 "circles" on Google+, the BBC reported.

Unlike some other stars, the best-selling singer has said she personally updates her account.

Last month, she revealed she was preparing to launch her own social network, Little Monsters.

A preview holding page for the new site suggests it may resemble popular image-sharing site Pinterest. Fans have been called on to sign up and receive an invitation to test the site.

Lady Gaga's latest album, 'Born this Way', has sold about 8 million copies - thanks in part to a considerable social media marketing effort.

As well as her huge presence on Twitter, Facebook and Google+, the 25-year-old has also teamed up with social gaming giant Zynga to launch GagaVille - a Lady Gaga-inspired take on the massively popular game Farmville. (ANI)
