While some Swifties believe "Mr. Perfectly Fine" is Joe Jonas, others wonder if she is addressing John Mayer, whom the singer reportedly dated during the 2009 - 2010 winter. The "Mr. Everything revolves around you" lyric is a potential clue: Swift's Speak Now
track "Dear John
," which is believed to about Mayer, begins with the line, "Long were the nights when my days once revolved around you." It should be noted that Swift recorded Fearless
in 2007 and 2008 - long before her relationship with Mayer.
