According to US Weekly, they are!
The mag recently published a story saying Grammy Awards execs were asked to keep Taylor and Carrie away from each other at the show this weekend!
"Taylor feels Carrie is always rude to her, so she steers clear of her," a supposed pal of Swift's told them.
GossipCop.com is shutting down their story, saying they really talked to someone close to Tay and she has no hard feelings towards Carrie at all!
We kind of believe both stories...
While we don't think they'd insist on not crossing paths at the awards show this weekend, we do think there's probably some jealousy and bad blood between the two.
This isn't the first time we've reported about it! Carrie admitted in a recent magazine interview that she and Taylor aren't BFFs.
Taylor did come into the country music world right when Carrie was on top, totally stealing her thunder. Because of that, we can so see her having some attitude towards Tay.
What do you guys think? Is there bad blood between the country cuties? Are you on Team Taylor or Team Carrie? Let us know!
