Britney Spears has revealed her sons think she's being a superhero when she's working.
The pop princess and US X Factor judge is mum to Sean Preston, seven, and Jayden James, six, her sons from her previous relationship with Kevin Federline, and told Lucky magazine they are still trying to understand her fame.
"They're in the middle right now of trying to figure it out," Britney said.
"They try to figure out where I go when I go to film X Factor. They're like, 'Mommy's going off to be a superhero.' And then I get back, and they just see me as Mommy. And then when I'm back working on the show, they say, 'Oh, Mommy's a superhero again!'"
The Toxic singer revealed that despite her stardom, she has a normal life at home with her fiance Jason Trawick and children.
She said: "I work out. I swim. I play with the kids, I cook and I garden. We play Connect Four. We play Candy Land. Last night we read The Night Pirates."
Britney also revealed she would have mixed feelings if her sons wanted to follow her into showbiz one day.
She said: "If there was something they really wanted to do and were passionate about, I'd encourage them to follow their dreams.
"But I'd also be there behind the curtain saying, 'No, don't go out there'."
