If you’re wondering why you've seen less of Britney Spears’ intimate parts lately, it could be because her father has resorted to performing a ‘knicker check’ on the singer before she leaves the house.

Jamie Spears' control over his daughter’s affairs extends to her revealing wardrobe in a bid to keep her covered up, according to a U.S tabloid.

“Jamie makes sure to ask Britney if she has underwear on before she goes out,” a source tells the National Enquirer.

The pop wreck’s assistant, Brett, is also reportedly on hand to remind her to wear underwear and a bra – much to Brit’s irritation.

The source adds: “Britney tries to ignore their requests, but her dad is adamant and insists she change if she’s falling out of her top.”
