Ashton Kutcher, who became an undisputed king of Twitter after famously beating CNN to 1 million followers last April, is getting tough competition from pop star Britney Spears.
Imdb.com reports that Kutcher had more followers than anyone else on the micro-blogging site, but it seems his days as Twitter's most popular user is in trouble.
Spears is slowly closing in on Kutcher - and the gap between their number of followers gets smaller every day. At the time of this posting, Kutcher had 4,890,797 followers, while Spears had 4,878,516.
While Kutcher is the only person who Tweets on his account several times each day, Spears only sporadically posts on her Twitter account, along with her manager Adam Leber.
