Los Angeles:
The Wide Awake hitmaker is amused by the fact that 91-year-old Ann Hudson - who appears in her new documentary film Part of Me 3D - "doesn't acknowledge" her success and can't understand the fuss that surrounds her famous granddaughter.
Katy said: "My grandmother is in the movie and she steals the show, she is living in Las Vegas and she doesn't acknowledge my success at all, which is exactly what I need.
"When she was at the Hollywood premiere she was like, 'Oh, why are you here?' and I was like, 'It's my movie,' and she was like, 'Oh is it?' She thought everybody was there to see her!"
The 27-year-old pop superstar is now planning to take a break from music because she fears being overexposed.
She added in an interview with The Sun newspaper: "I will take a catnap, take a pause, plug into the matrix - but I won't go away.
"What I need to do is let the dust settle and take the temperature of what the world wants musically.
"I am definitely going to recharge because you can get over-exposed and I am balancing that tightrope at the moment, having my own movie about myself."
