(breakingnews.iol.ie) - Heidi Klum is amazed to have landed the coveted title of the world's hottest model, because she is a mother to three children.The German catwalk star last month beat Brazilian babe Gisele Bundchen and Adriana Lima to land at number one on the Models.com list.Klum has a three-year-old daughter, Helene, with ex-boyfriend and Formula 1 boss Flavio Briatore, and two sons, Henry and Johan, with her husband Seal.And the 35-year-old is convinced landing the title is a major step forward. She says: "It felt great, especially after having three children. It's brilliant for all mums because women sometimes worry whether they can still be sexy after having kids or how they're going to be perceived by people for being a mum. "I had employers who thought if I had a child I wouldn't fit in the sexiest women category any more. But I think it's different these days."
