Los Angeles: Singer Katy Perry says there are days when she and her boyfriend John Mayer do not speak with each other at home as they need to give some rest to their vocal chords.
The 29-year-old `Roar` hitmaker, who reunited with Mayer after a brief split earlier this year, said the couple prefer to communicate through iPad during those silent days at home, reported People magazine.
"I understood that he couldn`t talk, and the only way he could communicate was through an iPad," Perry, 29, said in an interview on `The Ellen DeGeneres Show`.
"Some days I have to go on complete vocal rest, like no anything, no whispering. Whispering is actually really bad. There`s just a lot of silence in our house most of the time," she added.
