Katy Perry’s Late Night Bootycalls with John Mayer Are Ticking Off the Neighbors

What happens when you take two wild musicians known for their sexual exploits and put them in a house together?

Just ask Katy Perry’s neighbors.

Katy has been dating rocker John Mayer on and off since her split from ex-husband Russell Brand was finalized in June. It now appears the couple has reached a euphoric phase in the relationship; we call it “The Sex Years.”

In fitting fashion, John and Katy have been heard making sweet music of another kind in the early hours of the morning — much to the chagrin of neighbors in Katy’s West Hollywood neighborhood, a snitch tells Star magazine.

“Katy and John like to have very loud sex, keep very late hours and like to turn up the tunes.”
