Klum keeps weight on to avoid wrinkles

London: Supermodel Heidi Klum is happy to keep a little bit of weight on as she believes being too skinny causes lots of wrinkles.

The 37-year-old beauty, who raises four children with husband Seal -- says she is keen to carry a little extra weight as she knows that being too slim can leave you looking gaunt, reports femalefirst.co.uk.

"My tip is, don`t be too thin! It is always better to have a little meat on your bones. When you are just muscle, you end up being gaunt in the face, and that makes you look older by five or 10 years," she said.

While the German supermodel is conscious of looking old, she insists she doesn`t let it take over her life and has no plans to get Botox in bid to stop the ageing process.
