The `Project Runway` judge admitted that she is wary of another legal union - although she did love being married to musician Seal, whose separation (after seven years of marriage) was announced in January.
She told the weekly newspaper Bild am Sonntag: "I don`t know if I`ll get married again. Although I really enjoyed being married. I`m a dreamer. I loved our annual fairy tale weddings that were our big family parties. But sadly, it somehow didn`t work out."
The 39-year-old supermodel denied that she is dating Thomas Hayo, her `Germany`s Next Top Model` colleague.
She revealed: "He is not, nor was he ever my boyfriend. I think he is a great guy, but not for me."
Heidi said that she is generally satisfied with her life now as a single woman.
Heidi added: "I think everyone should work on their dreams. I try to. I look into the future, concentrate on my family and I have to say that I`m happy. There are worse things in life than a separation."
