You know someone’s in trouble if they need parenting tips from Britney Spears of all people. On Ellen on Tuesday, Heidi Klum proved she may be a great model and that she is a mastermind for Project Runway but apparently she’s totally clueless about some parts of parenting.

Heidi said that Britney arrived uninvited to her Halloween party but it was okay because they started swapping baby talk. Britney helped Heidi understand how disposable diapers work – seemingly Heidi was completely unaware of the velcro/sticky tabs on the sides of diapers. Britney explained how you used them to secure the diaper, which is good because Heidi was TYING the diapers on.

“You know these sticky things on the side? I never knew that they were there. To close them in the front, I was always putting string around. I had no idea,” Klum said to Ellen.
“It’s very clever,” she added. “I learned a lot of things.”

I weep for humanity.
