Heidi Klum gushed that it's "mind-blowing" seeing her daughter modelling.

The 47-year-old supermodel couldn't be prouder of Leni, 16, after she made her modelling debut in December and subsequently landed spots in runway shows and the cover of fashion magazines.

She told People: "She's been doing fantastic. She's been wanting to model for quite some time. And I finally said yes because she's now old enough, she's almost 17. She started with the German Vogue cover and she has another cover that's coming out in two months.

"She opened Berlin Fashion Week where I saw her walk for the first time, in heels like as a real fashion model. It's mind-blowing to me to watch her work, especially the first thing I did together with her and now she's doing things by herself, even though I go to the set."

Heidi claimed her daughter has been a supermodel-in-the-making from a young age after she showed off her skills behind the camera.

She explained: "It's amazing to watch her do it all. She's been coming to my sets for her entire life and she's not really afraid of the cameras being stuck in her face. I do 'Germany's Next Top Model' and she's done a lot of the shoots the models had to do. A lot of the times at the end of the shoots, she would be like, 'Now it's my turn!' off camera. She's done so much over the years, she loves it. She loves it!"

The teen made her debut as a model on the cover of Vogue Germany alongside her parent, with the pair rocking matching colourful trouser suits.

Leni told the publication: “It was only a matter of time before I would try it myself as a model. The first offer came when I was only 12 or 13, from a brand I loved to wear: Brandy Melville. Back then I begged Mom, but no chance! I now understand that it would have been too early.

 “For most other jobs, I’d have to stifle my crazy ways to look ‘professional.’ As a model, I can let everything out and just be who I am. The job is the perfect outlet for all the energy that I have in me.”
