The model celebrated her landmark birthday in June 2023, and Heidi has revealed that she's happy to embrace her age, rather than hiding from it.
The blonde beauty - who is married to 34-year-old musician Tom Kaulitz - told HELLO! magazine: "I feel lucky to be 50. We're lucky to get old.
"When I was younger, I would think: 'Fifty! That's like a grandma already!'
"Now that I am 50, I don't feel like a grandma, even though I could be one very soon. Who knows?"

Klum - who has children Leni, 20, Henry, 18, Johan, 17, and Lou, 14 - feels she actually has more freedom now than she did a decade ago.
The model also revealed that she's recently rediscovered her love of clubbing.
She said: "Now they're older, the days of me going to bed at 9.30am are over. So I feel like with them all being older now - maybe it also has to do with my younger husband, I don't know - it's just fun.
"It's fun to go to a club. I enjoy music most of the time.
"I'm going to the club and I look around and I'm like: 'Am I the oldest person here? I think I am.'"
Meanwhile, Klum previously described her husband as a "great man" and has rubbished criticism of their age gap.
Asked why it's such a big issue for so many people, Heidi told Glamour magazine: "I think it's often just spitefulness.Â
"Perhaps many people also think I've had too much luck in life. I have a great job, I get to travel the world, I can buy expensive things. And now I've also got myself such a great man."
