Taylor Swift has officially become a crazy cat lady. It really was just a matter of time. For some reason, #44 Diet Coke hired Taylor to be in a commercial. WTF Diet Coke?? You're a betch's best friend so who decided it was okay to let a delusional dater represent our brand? The premise of the commercial is that a sip of Diet Coke is so good it makes kittens appear and makes you forget that you'll be alone forever. Sure. So I guess when Taylor said she was “single and loving it” what she really meant was that she's given up on herself and is now breeding cats to fill the void.
