Katy Perry had no qualms about being captured without make-up in her forthcoming documentary.
The Last Friday Night singer appears bare-faced in her 3D concert film Part Of Me.
She told Nessa on US show WiLD 94.9 that she wanted to look "real".
"Look, I don't always want to look bloated with zits, but it's real, it's human, right?" the pop star said.
"We're not always so pretty and sometimes that can bring people closer together... I'm not a perfect person."
Katy, who split from husband Russell Brand, refused to reveal details about her sex life. But asked what type of man she was attracted to, she said: "I like a good boy but sometimes I get bored."
And she baulked at the thought of listening to her own music in the bedroom.
"I'm not a narcissist!" she said. "OK, I'm a narcissist, but that would be over the line. Having sex to your own song, that's horrible."
