Say what you want about Lady Gaga's bizarre fashion sense, the lady knows how to draw fans to her Web site. The 23-year-old glam-singer has almost 3.5 million fans on her Facebook page.
Lady Gaga posts about her music career, informing readers about her upcoming tour dates and progress in the studio, and also offers fans the occasional sartorial tidbit.
And, just in case her fans worry their devotion to the singer is unrequited, Lady Gaga dedicates status posts to her fans.
"In every minute of the day, the truth is that I'm dead, until I'm here on stage, with you, then I'm alive instead," she revealed in a post.
Adam Sandler has made a career playing the "Average Joe" character in his movies, but he's certainly breathing refined air at the top of the Facebook summit. Sandler, who stars in the upcoming comedy "Funny People," has accrued roughly 3.3 million fans on his Facebook page.
His page is full of videos, interviews, photos and movie clips, and includes a brief biography under the info section, which may help fans learn more about the popular actor.
Ashton Kutcher is no stranger to the viral community. In 2009, the 31-year-old actor and former model became the first Twitter user to surpass 1 million followers, eking out the news network CNN, whom he had challenged to a Twitter popularity contest.
It's surprising, then, that Kutcher doesn't have a larger following on Facebook, though his nearly 3 million fans are still enough to put him at No. 7 on our list.
Out of all the celebrities in the top 10, Kutcher is perhaps the most devoted site moderator. His postings offer a glimpse into his private life, like a link to a photo album from Kutcher's Fourth of July visit to the White House.
