If I were Carrie Underwood, I'd hate Taylor Swift.

Taylor is the arguably the biggest female pop star on the planet right now, right?

And her vocal skills are incredibly WEAK compared to those of Carrie Underwood - who struggles to get consistent pop-crossover radio love w/ her songs.

Word is, they hate each other.

Carrie was asked by CBS about it & said this-

I don't believe her. Lol.
