Klum is hoping for a girl

Pregnant supermodel Heidi Klum and her husband Seal are crossing their fingers for a baby girl, when the new addition to their family arrives later this year.

The singer revealed Klum is expecting her fourth child - the couple's third - during a New York concert last week, ending speculation.

And Klum - mother to Leni, five, Henry, three, and Johan, two - has already decided she wants a second daughter.

The German star told Us Weekly magazine: "We'd be happy with either, but it would be a lie if I said we weren't all hoping for a little girl - especially Leni, because she would love to have a little sister.

"She'll say: 'I hope it's a girl so she can be in my room, and I'm going to help you and I'm going to change the diapers and I'm going to be a really good sister.'"
