Singer John Mayer has more than 135,000 followers on Twitter, the free online blogging service that he uses to keep fans updated on his up-to-the-minute happenings. Over the weekend, website Country Music Is Love reports that he piqued the interest of his fans -- and fans of Taylor Swift -- with this "tweet":

"Waking up to this song idea that won't leave my head. 3 days straight now. That means it's good enough to finish. It's called 'Half of My Heart' and I want to sing it with Taylor Swift. She would make a killer [Stevie] 'Nicks' in contrast to my 'Tom [Petty]" of a song."

Swift gave her own shout-out to Mayer on her Twitter page today: "Listening to 'Comfortable' by John Mayer."

We'll keep following these two on Twitter (and elsewhere) to track the progress of their potential duet.
