Rocker John Mayer is getting his own back on the press by spreading false rumors about himself.

The singer - who is dating Friends star Jennifer Aniston - is so sick of reading untrue reports that he has decided to make up his own.

Mayer filled gaps between songs at a gig in St. Louis, Missouri on Thursday night by telling the audience made-up facts about his life.

After telling fans he is scared of all things green, that he wrote the Kenny Loggins hit Danger Zone, and was building a time machine, Mayer announced, "When I was a child I would kill small animals and wear their teeth as necklaces. True. Print that. And I've always felt deep down that I was born a woman."
