Sooo Taylor Swift, Katy Perry AND their mutual ex-boyfriend just hung out

This is kinda, sorta massive?!

By Bianca Mastroianni

Katy Perry and Taylor Swift have a very, very long standing beef.

Legit nothing has been resolved between the two over the many years that they've hated each other, and it doesn't help that they both share an ex-boyfriend too. But you know what's a great idea? Throwing them all together in the same room lol. This happened.

Taylor, Katy and John freaking Mayer all attended Drake's 30th birthday party, and we're expecting all the #drama right now.

You SEE, this is one of those moments when ppl say "pic or it didn't happen," and there are so many damn pics.

Oh, to be a fly on the wall at that party. Not sure how Taylor fits in with this crowd of people, since we know Katy and Rihanna are total BFFs so that makes sense...

We can imagine Drake writing the guest list with an epic grin on his dial.

More details are surely going to come from this, so, TBC...
