In the known feud between pop stars Katy Perry and Taylor Swift, both participants semi-frequently make bold public moves. And while there's no clear frontrunner, as these two are perfect matches for each other's wonderfully Machiavellian and Instagram-savvy minds, Katy Perry's disses tend to be a little bit funnier. There was the infamous Regina-George-in-sheep's-clothing subtweet, the high-waisted bikini dancers, and now a subtle "eff you" in the form of a casting decision.

Perry has a new video for H&M, in which she plays an intense holiday fairy and sings a new KP original, "Every Day Is A Holiday."
