Klum son Henry a fashionista in-the-making

Heidi Klum's four-year-old son is obsessed with fashion.

The 'Project Runway' host - who raises daughters Leni, six, and Lou, nine months, and boys Henry, four, and Johan, three, with husband Seal - admits all her children have very different attitudes to their appearance and Henry shows a big interest in his.

She explained: "Johan doesn't care much about what he's wearing. Henry is very particular, even with his pyjamas.

"Leni loves dresses and loves being girlie. She came to the 'Project Runway' set and the fashion show and wasn't too impressed. I don't think she thought the clothes were girlie enough."

Despite raising four children, the supermodel claims it doesn't mean she can't be stylish and has made her life easier by reducing her wardrobe.

She said: "Be organised. Narrow it all down to make it work. Get rid of all the things that are too 'mumsy.' I got rid of all my over-baggy, nasty, jim-jam things that are frumpy, so when you put things together, everything is working."

The 37-year-old beauty also revealed she would love US First Lady Michelle Obama to join her on the judging panel for 'Project Runway'.

She told website Stylelist: "My number one dream would be first lady Michelle Obama. I think she's super-hip, cool, and fashionable."

Heidi is also a fan of Christian Siriano, who won the fourth series of 'Project Runway' and is happy to wear his clothes.

She added: "He has the most business-y brain. He doesn't forget to send things. He sends look books. He makes sure when he has a fashion show, he invites you.

"Others mosey on with their business as usual. He sends things for me to see and try. I'm busy myself and he makes it easy. He's clever."
