Katy Perry Rocks Boston And Sabrina Takes Some Concert Video![VIDEO]

Good times in Beantown last night!

Boston was the place to be last night. Not only were the Red Sox and Yankees playing a few T stops away, but the one and only Katy Perry took her tour to the TD Garden for what looks like a pretty awesome show.

Sabrina was on the scene and took some cool video of Katy's opening song.
