This is the breakup that just won't end. Even though Taylor Swift and John Mayer haven't been together for over three years, they keep fueling the gossip fire by writing songs about each other.

Can we make a rule where singer-songwriters can't date each other anymore to avoid this in the future?

The most recent break-up track comes from John Mayer in the form of 'Paper Doll.' Why do we say it's directed at T. Swizzle? Let's take a look at the lyrics, shall we? Mayer sings, "You’re like twenty-two girls in one / And none of them know what they’re runnin’ from / Was it just too far to fall? / For a little paper doll." Yeah, John could have used almost any other number, but he settled on 22, which also happens to be the title of Taylor's massive hit song.

But it gets better. Remember how Taylor sang, "You paint me a blue sky and go back and turn it to rain," in her track 'Dear John'? Well, Mayer made a reference to this in 'Paper Doll' with the line, "Someone’s gonna paint you another sky." Whaaaaat. Seems pretty glaring to us, though it could be a coincidence...or not!

We must also mention that John Mayer's lyric video for the song 'Paper Doll' features prancersizing and is all kinds of awesome... seriously!
