Lady Gaga

Lady Gaga just pulled ahead of Britney Spears and now has the most followers of anyone in the world on Twitter. The "Alejandro" beat Brit by 34,000 followers and now has 5,735,554 followers, while Brit has 5,701,236. Gaga celebrated the victory by making a video for all of her loyal followers.
Addressing her fans as her “little monsters”, the pop star, who appears in a makeshift crown with a twitter logo on it and waves a magic wand in the video, says: “Hello world, this is Lady Gaga, queen of twitter. I wanted to thank all my beautiful little monsters for following me. Thank you for beginning my reign as twitter queen. I vow to always tweet and tweet again.”
Gaga currently picks up new followers on twitter at an average of around 171,000 a week, according to website famecount.com which analyzed the data. Although she is the most followed star on twitter, she is not the fastest growing; that title goes to teen pop sensation Justin Bieber, who is amassing an average 800,000 new followers each month. Other popular tweeters include actor Ashton Kutcher and musician Taylor Swift, who both have over 3 million followers each.
