wants more children.The former Victoria's Secret supermodel - who has two children, two-year-old Henry and one-year-old Johan, with husband Seal and a four-year-old daughter Leni from a previous relationship - has no intention of finishing her family.She told Redbook magazine: "So many people say, 'I am so done.' That hasn't come out of my mouth, and it hasn't come out of Seal's mouth, either. I feel like we still have one coming."Heidi recently revealed she is addicted to having children.She said: "I do miss being pregnant. Children are very addictive. Once they start growing up, you miss when they were little."The 34-year-old beauty also said she considers Seal to be Leni's real father, even though Formula One team boss Flavio Briatore is her biological father.She added: "Seal is Leni's father. Seal and I feel very lucky that we found each other. He's my best friend. He would never go in through a door first. He always opens the door for me and steps back so I walk through."
