Lady Gaga has become the first Twitter user to reach 20 million followers.
The Born This Way hitmaker - who joined the social networking site in 2008 - has beaten Justin Bieber, who is languishing behind with 18.1 million followers, to the milestone with her @ladygaga account.
Gaga - whose real name is Stephanie Germanotta - uses the account, which she started on March 26, 2008, to interact with her supporters, who she refers to as Little Monsters.
Since overtaking Britney Spears as the most-followed person on the website in August 2010, the singer has held onto the top spot.
Gaga is well ahead of her fellow singers Katy Perry, who has 15.5 million followers, as well as Shakira and Rihanna, who both have more than 14.5 million.
