If true, this will be Heidi’s fifth child. The German supermodel is already mum to Leni, 14; Henry, 12; Johan, 11; and Lou, 8.
Despite their 17-year age gap, Heidi is smitten with the Tokio Hotel guitarist.
"He is the kindest, sweetest, most caring, loving person. I feel so lucky. I don’t know the last time I was this happy in my life. He is absolutely wonderful. Maybe it is because he is German and we understand each other in a different way. But so far so good," she told People.
