After bursting on to the scene in 1998 as the cover girl of Sports Illustrated, Heidi Klum quickly won global acclaim as one of the most influential supermodels of her generation.

Now, almost three decades later, she is set to make a return to Project Runway – the TV show that previously won her an Emmy Award.

During her eight-year hiatus from the programme, Heidi, 52, has been supporting two of her children as they prepare to follow in her footsteps by breaking into the modelling world.

“The best advice I have for anyone who wants to model is to work on your posture. So I’m always reminding my kids to stand up straight, make yourself taller, be proud,” she says.

“But most of all, I tell them to be careful, to be happy and to never be afraid to say no to things they don’t want to do.”

Heidi is a devoted mother of four children: she and her former husband, Seal, have sons Henry, 19, and Johan, 18, and daughter Lou, 15. The singer also legally adopted Heidi’s eldest daughter, Leni, 20, from her previous relationship with Flavio Briatore.
