Lady Gaga's little monsters have helped make her the most popular person in the Twitterverse!The 26-year-old singer is the first one to have over 25 million followers on Twitter. The social media milestone didn't go unnoticed by the pop star, who is currently on her Born This Way world tour. From the road Gaga tweeted: "#25milliontweetymonsters wow! I'm officially feeling like the luckiest girl in the world today."
The other celebrities rounding out the top five most followed are Justin Bieber (22.6 million), Katy Perry (20.5 million), Rihanna (19.8 million), and Britney Spears (17.2 million). President Barack Obama isn't that far behind with 16 million.

The microblogging site has grown tremendously in a short period of time. Just three years ago, Ashton Kutcher, one of the early adopters of Twitter, was all over the news when he hit a then-record breaking 1 million followers. Kutcher, who now trails far behind with about 10.8 million, was soon surpassed by Spears, but not for long. Three months later, in August 2010, Gaga took the lead from Spears and has been at the head of the pack ever since. When Gaga first hit No. 1, she posted a funny video in which she declared herself "Lady Gaga, queen of Twitter." Wearing a white lace hat with the Twitter logo on it and waving a wand, she thanked her "beautiful little monsters for following me."
