Have you ever used MegaUpload? Chances are you have, if this new video claiming it has 1 billion users is true.

In case you weren't aware of the site, a lot of celebrities use--and love--MegaUpload too. The file-sharing site has been catching a lot of flack from the MPAA and the RIAA recently for enabling pirates.

However, in an ironic turn of affairs many of the industries' biggest names including P. Diddy, Kim Kardashian, Kanye West, Lil John, Alicia Keys and Snoop Dog have come out in support.

Even stranger still, they declared their support in song. Its a bit silly, but it at least gets its point across how fast and useful MegaUpload is. Also that celebrities will endorse anything for a quick buck.

Update: The video has now been removed from YouTube at the behest of Universal Movie Group. Kim Dotcom, the owner of MegaUpload came out against UMG calling their actions "illegal" and, in a humorous riposte, published the video on his own site Mega Video.
