Poor Taylor Swift! We know she's been having boy trouble lately- but now girl trouble to boot?!
And boot is exactly the right word, because this here is what we call a country feud- with Carrie Underwood!
According to a source close to the Grammys, organizers were told to keep the two as far apart as possible because "they hate each other!"
"Taylor feels Carrie is always rude to her, so she steers clear of her."
Ouch! Sounds like this award show ain't big enough for the two of 'em!
We hope they can bury the hatchet before Sunday!
