Britney SpearsBritney SpearsShe's been publicly criticised for her poor parenting skills.

But when it comes to changing babies, Britney Spears is a dab hand.

Appearing on the Ellen DeGeneres Show recently, model Heidi Klum said Brit gave her a tip or two when it came to the all-complex topic of nappies.

Heidi, who has three toddlers under the age of five, recalled how Brit spread some words of wisdom when she turned up uninvited at Heidi's Halloween bash.

"We were talking about babies and diapers and she explained to me a lot of things about diapers I that didn't know," Heidi told Ellen.

"You know these sticky things on the side? I never knew that they were there," Heidi said.

We sincerely hope Heidi's having a bit of a joke on us here.

Either that or she's had thousands of minions to do her dirty work for her.

On the bright side, it's good to know mum-of-two Brit is familiar with the odd spot of nappy duty.

That's a brownie point to be had in the court reports, surely?
