Taylor Swift might not ever, ever get back together with her ex-boyfriends and according to a new report she was “bitter” about even being near John Mayer!

The 23-year-old singer was furious at the Academy of Country Music Awards on April 7 when she found out John was going to take the stage before her.

"She said she had to go on earlier than him," a source told Usmagazine.com and pitched a “stink” about his performance.
