What happens when you take two wild musicians, known for their sexual exploits, and put them in a house together? Just ask Katy Perry and John Mayer's neighbours.
The new couple were apparently heard making sweet music of err… another kind, in the early hours of the morning in Katy's West Hollywood home.
Katy and John like to “have very loud sex, keep very late hours and like to turn up the tunes,” reports Star magazine.
At least the on-again off-again couple are enjoying themselves.
After divorcing from husband Russell Brand earlier this year, John has been Katy's first serious partner since the split.
Let's just hope the notorious ladies' man has matured beyond his past womanising ways.
