Is John Mayer about to propose to Katy Perry?

It's been about six months since crooner John Mayer started dating singer Katy Perry but he may be preparing to pop the question already.

According to a More! magazine source, John likes Katy's independence and the fact that she's not needy and clingy like the other girls he dated.

John has dated the likes of Jennifer Aniston, Taylor Swift, Cameron Diaz and Jessica Simpson. Katy meanwhile, filed for divorce from her husband, British comedian, Russell Brand in December 2011.

But the source says, the 28-year-old Katy is ready to start a family with the 35-year-old.
