Katy Perry rocks out to AC/DC wearing devil horns at the Grammy Awards (GIF)

Katy Perry was having so much fun at the Grammys on Sunday while she was rocking out to AC/DC with everyone else

The 2015 Grammy Awards got kicked off in a huge, nostalgic way on Sunday night as legendary rockers AC/DC got things started with a performance for everyone in attendance and those watching at home. The people that were in attendance, though, were thoroughly enjoying the performance that was happening in front of them, especially Katy Perry.

Oh, and as you would expect, Perry took her rocking out to a whole other level, and it fit the guys from AC/DC pretty well, to say the least.

When the camera was panning its way through the crowd that was there, Katy Perry was caught jamming out with some devils horns on her blue head. Oh yeah, she has blue hair tonight, too, in case you were wondering.

Now see, Katy Perry gets it, she just gets it. That’s how you enjoy a performance from one of the greatest rock bands of all-time.

Sadly, though, there are probably a lot of people out there that are going to have to Google AC/DC and that makes me sad, and it probably makes Katy Perry sad too.
