Heidi Klum believes her youngest daughter Lou will become President of the United States

She told the new issue of Britain's HELLO! magazine: "I think she's going to be president some day. Right now, Lou is 15 and she's mostly into arts and crafts, debating, her choir and so many different things."

Despite Lou not wanting to become a model, she and her siblings are always reminded to maintain good posture by their mom.

Heidi said: "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."

The former Victoria Secret angel stresses to her children that it is OK to say no to things.

She continued: "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 was surprised that her eldest son Henry wanted to try modelling because she thought he wanted to become a musician.

The America's Got Talent judge - who has been married to Tokio Hotel guitarist Tom Kaulitz, 35, since 2019 - said: "I always thought he was more into music, but he came to me and said he really wanted to give modelling a shot.

"I've been there for him a little more because it's new to him."

Meanwhile, Heidi's eldest daughter Leni - who she has with her ex-partner, businessman Flavio Briatore, 75, and was later legally adopted by Seal - is following in her mom's footsteps, and Heidi is proud of what she has achieved.

Speaking about Leni - who has landed campaigns with Dior, Fila and Intimissimi - said: "Leni is doing so well.

"She's incredible but she always knows I'm there for advice."

Johan is now driving - which scares Heidi - and is going to college. She said: "My son Johan has just passed his driving test, so he's driving around, which is scary.

"He's off to college, so now it's just me and Lou at the dinner table, most of the time."
