Top 10 Most Popular Celebs on Facebook

July 6, 2010— -- To the list of accolades on pop star Lady Gaga's colorful resume, here's one more she can add: the most popular living person on Facebook.

The singer on Friday reached 10 million fans and is now surpassed only by Michael Jackson.

After hitting the mega milestone, Gaga posted a video to her Facebook page thanking her "little monsters" for their love and support.

Just a year ago, with 3.5 million fans, she was number 6 on the list of the most popular celebrities on Facebook.

She's not the only celebrity to have gained millions of fans on Facebook over the past year. With Facebook's help, we've compiled a list of the top 10 most popular individual celebrities on the social networking site.

Take a look below.

Even in death, Michael Jackson continues to be Facebook's most popular celebrity. With 15,048,539 fans, the King of Pop is comfortably ahead of his closest contender, Lady Gaga, by more than 4 million fans.

According to a Facebook spokeswoman, the King of Pop's fan base rose from 800,000 the day before Jackson's June 25, 2009, death, to more than 10 million not even a week later.

Jackson's page includes previously unavailable music videos, and it updated fans on the latest news surrounding tribute events for the anniversary of Jackson's death.

Lady Gaga may take some flack for her oddball fashion sense, but her Facebook fans seem drawn to her no matter what she wears.

On her fan page, she 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.

Only a few days after hitting 10 million fans, it looks like she's about to hit another benchmark. As of Monday morning, the star had 10,968,138 fans (or people who "Like" her) on Facebook.

The "Fast and Furious" star also reached a milestone over the holiday weekend.

On Sunday, Vin Diesel hit 10 million fans, announcing on Facebook, "WELCOME TO OUR MILLENIUM!!!"

With frequent status updates, pictures and video clips, the action star has drawn a stellar online following of about 10,300,000 fans.
