Britney Spears says her two young sons are convinced that she’s on a mission to save the world when she leaves home for work.

The star is mother to boys Preston, seven, and Jayden, six.

Britney currently judges alongside Demi Lovato, L.A. Reid and Simon Cowell on US TV talent show The X Factor.

The songstress thinks her children’s interpretation of what she does for a living is absolutely adorable.

“They try to figure out where I go when I go film X Factor,” she laughed to Lucky magazine.

“They’re like ‘Mommy’s going off to be a superhero.’ ”

While sitting on the X Factor panel, Britney makes it a point to look her best.

She looks to certain divas for style inspiration.

“[Jennifer Lopez is] a classic beauty,” she gushed. “[And I love Sarah Jessica Parker’s taste in clothes because] her looks are really bright and funky and young.”
