Something tells me that Mark Zuckerberg is trying to prove he had the best week ever. Not only did the Facebook creator have his company go public AND get married, but today, we find out that none other than Billie Joe Armstrong played at the wedding!

According to Entertainment Weekly, the Green Day frontman played at the wedding completely for free!  It turns out that the two have known each other for a long while, and Armstrong did it as a little wedding gift for the bride and groom.

I wanted Armstrong to play at my wedding…I ended up getting a DJ with an iPod.  See what happens when your personal net worth is around $20 billion?
