Heidi Klum is opening up about a pretty awkward mom moment.
The America's Got Talent judge, 50, appeared on Wednesday's episode of Call Her Daddy, where she FaceTimed 19-year-old daughter Leni.
"She found my sex closet," the model admitted.
"I did when I was younger and I thought it was the coolest thing ever. I was going through it with my friends. And I was like, 'Mom, what is this? A microphone?'"
"I really had no idea what it was. My mom got so mad at me after, like, You can't go in my stuff.'"
"I was like showing it off to my friends like, 'Look at how cool this is. My mom has a whole cupboard, she has a whole drawer.' And I snuck them into my mom's room and opened the drawer, and we were all taking videos."

Speaking with PEOPLE at the 36th Nickelodeon Kids' Choice Awards in Los Angeles last March, the former Victoria's Secret Angel raved about how "very proud" she is of Leni, who's currently studying interior design in college while pursuing her own modeling career.
"I'm very proud of my daughter and her modeling," said Klum. "And she's studying at the same time, she's juggling already."
