Washington, Apr 23 : Supermodel Heidi Klum, who is pregnant with her fourth child, has revealed that she and her husband Seal are keen to have a baby girl.

Heidi, who already has a daughter Leni, 5, with former lover Flavio Briatore, revealed that her daughter is keen to have a little baby sister.

"We''d be happy with either, but it would be a lie if I said we weren''t all hoping for a little girl," Contactmusic quoted Heidi, as telling Us Weekly.

"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," Heidi added. (ANI)
