According to  Us Weekly, Taylor Swift and Carrie Underwood are NOT on good terms and they are planning to avoid each other at Sunday's 2013 Grammy Awards.

According to an insider, Grammy execs were ordered to keep Swift, 23, and Underwood, 29, "from crossing paths" at the Feb. 10 show "since they hate each other!"

Says a Swift pal, "Taylor feels Carrie is always rude to her, so she steer clear of her." (A Grammy rep counters, "No requests were received from either artist.")

At last year's Country Music Association Awards in Nashville Nov. 1, co-hosts Underwood and Brad Paisley mocked Swift's recent split with Conor Kennedy.  See it play out below...

I don't know if I put much weight in this story?  What do you think?
