It’s one of the biggest nights in the International music industry, and earlier this evening musicians from all over the world converged on the Echo Arena in Liverpool, England for the 2008 MTV Europe Awards.

Taking care of the hosting duties was none other than Katy Perry. And the “I Kissed a Girl” songstress had plenty of sass and costume changes (a total of 12) to fill the 2-hour time allotment.

If there was ever any doubt that Beyonce and Jay-Z tied the knot a few weeks ago, it had been put to rest. The newlyweds filed their marriage license this past Friday.

The paperwork, which lists their wedding date as April 4th, was officially filed with the Scarsdale Town Clerk, who says even though they waited past the usual 5-day requirement, there shouldn’t be a problem.
