Britney Spears taught Heidi Klum how to use a Diaper

This morning, Heidi Klum was on the non-striking Ellen DeGeneres Show where she talked about her infamous Halloween party and her Britney encounter there.

Klum, 34, got the tips after Spears showed up uninvited to her Halloween bash at L.A.'s Green Door lounge.

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

"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.

"It’s very clever," she added. "I learned a lot of things."

Hmmm. Interesting.
