How much did this damn video COST?!

Taylor Swift got half of Hollyweird to come out for her new music video for the single "You Need To Calm Down" and we are THERE for it!

The pop star -- increasingly in the pop genre and less in the "country" music category -- celebrates just being nice to each other and making up ... as she did with her frenemy Katy Perry in this clip! FINALLY! I mean, lead by example, right?

Swift and Perry finally put their beef to rest and T-Swiz tells us all to not "step on our gowns" and now throw shade and we think this is a delightful message for a Monday morning and every day!
