Britney: Being a sex kitten is my job

Britney Spears thinks it's her job to look more like a "sex kitten" than she really is.

The 31-year-old star's video for her new single 'Work B***h' shows her flaunting her figure in sexy outfits while she whips her dancers and she claims this is a different role to what she plays at home where she is mother to sons eight-year-old Sean and seven-year-old Jayden - who she has with ex-husband Kevin Federline.
