This story is unreal!
Paul McCartney is a guy who recorded a couple of songs with Kanye West (He was also in a little band called The Beatles, they had a few hits) but I guess it wasn’t enough to get past security.
Tyga apologized with a couple of tweets.
I don't control the door. I had no knowledge SIR PAUL was there. I just performed and left.— T-Raww (@Tyga) February 16, 2016
Paul ended up going to a different party and then went home and cried over his 18 Grammys, I think.
