Carrie Underwood has brushed off rumours of a feud with fellow country star Taylor Swift, insisting she's actually a fan of her country music peer.

I really like I Knew You Were Trouble. It sounded a lot different for her. I liked the branching out, trying some different sounds"

The We Are Never Ever Getting Back Together hitmaker was reported to be hoping to avoid the American Idol winner at Sunday's Grammy Awards in Los Angeles amid claims Swift was not a fan of Underwood's attitude.

A source told Us Weekly magazine, "Taylor feels Carrie is always rude to her, so she steers clear of her".

However, Underwood insists there is no friction "that I know of at least" and she reveals she loves Swift's latest single, saying, "I really like I Knew You Were Trouble. It sounded a lot different for her. I liked the branching out, trying some different sounds".
