Leona Lewis says she thinks that no songs are sacred and that all artists should expect their tracks to be covered.
It's after she released her cover of Nine Inch Nails' Hurt, which she performed at The X Factor final.
She's also released versions of songs by Snow Patrol and Oasis in the past.
"People write music and the music is out there for people to interpret it how they want to," she said. "As long as it's coming from a genuine place."
Speaking about Hurt, a track taken from Nine Inch Nails' 1994 album The Downward Spiral, Lewis added: "I actually am a big fan of that song and a big fan of the Johnny Cash cover."
Asked if she was a fan of Trent Reznor's US rock outfit she joked: "Ah yeah, I'm just always rocking out.
