Seal & Heidi Klum, a baby makes 4

Seal and his supermodel girlfriend Heidi Klum reportedly are desperate to have children together.

Klum already has a 7-month old daughter, named Leni, by Formula One 'playboy' Flavio Briatore. But they split while she was still pregnant and 41 year-old Seal (did you know his real name is Sealhenry Samuel?) has stepped up to the plate and become a wonderful replacement father for little Leni.

Friends say Heidi Klum is impressed by the singer's parenting skills and wants to give him a baby of his own.

I've seen loads of photos with Heidi, Seal and the baby. He's always holding her, loving her and basically playing 'daddy' to Leni. Too bad her real father isn't there for her, but Seal seems to be a stand-up guy. I can't say that I think they look like a "happy family" as they're a bit of an odd mix - at least that's my opinion.. but as they say "LOVE is Blind!"
