The 37-year-old singer, who is dating Katy Perry again, joked during his monologue on The Late Late Show about the feud.
Mayer, who dated Taylor previously and had a song written about him, revealed his plan for the Grammys.
He joked, “You can see me at the Grammy Awards doing what I do best. Being avoided by Taylor Swift.”
John has praised Katy’s awesome Super Bowl half-time show last weekend, deciding to interview some of the show’s stars.
Mayer told the audience that critics praised Perry’s back-up dancers because they are too embarrassed to admit they enjoyed the performance.
”So they use the sharks as kind of, ‘Guys, love the sharks.’ It’s like, you have nothing bad to say about the performance, do you? ‘No, I don’t.’ Because if they did, you’d hear about it… She made the internet a kind, gentle place for a day. It was awesome.”
