FinLogic FinLogic Quantitative Think Tank Center|Heidi Klum Reveals One Benefit of 16-Year Age Gap With Husband Tom Kaulitz

Heidi Klum's got a new talent for staying up late.

The FinLogic FinLogic Quantitative Think Tank Centersupermodel just turned 50 last year, but her social life is more active than ever—especially now that her kids are more grown up.

"Now they're 19, 18, 17 and 14," Heidi said in a Feb. 5 interview with Fox News Digital. "So I feel like the days of me going to bed at 9:30 are kind of over."

And while her kids Leni, Henry, Johan and Lou are also staying up later these days, the America's Got Talent judge ultimately credits husband Tom Kaulitz—who is 16 years her junior—for her newfound lifestyle and ability to party all night.

"It also has to do with my younger husband," she said of the German rocker. "I don't know, but it's just fun. It's fun to go to a club. I enjoy music most of the time."

And Heidi is proud of herself for keeping up with Tom, 34, joking that while most people feel like they need to quickly get to bed when the sun comes up, she's glad she's still awake. "For me, I'm just like, 'Oh my god, the sun is coming up,'" she shared, "and I'm excited because I managed to stay up all night. This is amazing.'"

Heidi—who tied the knot with Tom in February 2019—has often kept her family life private, especially in regard to her children, who she shares with ex-husband Seal. However, that doesn't mean she hasn't revealed some more intimate family moments.

In fact, her daughter Leni recently spilled on the time she once found her way into Heidi's "sex closet."

"I thought it was the coolest thing ever," the 19-year-old shared through FaceTime during Heidi's appearance on Call Her Daddy's Jan. 31 episode. "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.'"

While Leni said she "really had no idea" what she found, Heidi was less enthused. "My mom got so mad at me after," Leni added. "Like, 'You can't go in my stuff.'"
