Singer John Mayer has revealed that he has no problem with his ex-girlfriends writing songs about him.
The 36-year-old singer said he actually hoped those songs would become chart-toppers, reported Ace Showbiz.
"I have super strength for gang-ups, I'm fine. That's what you're supposed to do, man, you're supposed to write songs. You're just not supposed to tell everybody you're doing it," he said.
Mayer is already the subject of Taylor Swift's 'Dear John' which is featured on the pop star's 2010 album Speak Now.
Now, another ex-girlfriend Katy Perry is reportedly working on a song about him as well.
