Taylor has Valentine's Day and The Lorax and is a Covergirl.
Katy has Adidas, she's ambassador of Pop Chips, Numerous NUMEROUS covers this year, two perfume lines, Smurs 1 and 2 (soon to come out, another hit movie), her own nail brand, and much more
The answer is obvious. The statistic speaks for itself. Why should I bother to explain? I'm having a hard time searching for a field where Katheryn is superior to Taylor.
