True to his name, the King of Pop’s Facebook Page has now grown to be the most popular page on Facebook – outpacing Barack Obama’s page by about 100,000 fans. A week ago, we reported that Michael Jackson’s page was the fastest growing page on the site with nearly 2.5 million fans. Now, the page has gained 4 million more fans and reached a total of 6.5 million fans – the largest fan base on Facebook to date.

Here’s a look at an PageData chart tracking the dramatic increase in number of fans in the past week:

Meanwhile as fans are still posting tributes to the pop star on the page Wall, the Page’s administrator admin has been sharing updates on ways for fans to memorialize Jackson: promoting a free Facebook Gift (a sequined glove) that users can send to their friends and a widget that reflects upon the singer’s career, as well as urging fans to post their MJ memories on MichaelJackson.com.

Around the country – and around the world – people are mourning the death of Michael Jackson, and we’re seeing that Facebook is being used as a platform where these emotions can be shared. At this point, it’s not clear whether the page will be able to stay active and keep up with its over six million (and growing) fans. The first person voice of Wall posts is also somewhat awkward in the case of individuals who have passed away.

Nevertheless, fans are flocking to celebrate Jackson as his memorial service takes place this morning. Fans can also watch the Jackson memorial online at CNN Live with Facebook’s “live stream” integration here.
