British singer Seal and his German fiancée, model Heidi Klum, are expecting a baby, Internet portal Ananova reports.

The Grammy award winning black singer, 42, had only in January announced that he was planning to tie the knot with Heidi, 31, who already has a 10-month-old daughter Leni.

Klum said on her website: "Heidi, Seal and especially Leni are proud to tell you that we recently found out that we are expecting our second child. There is nothing that gives us greater happiness than the realisation of our dream.

"Thanks to all of you that have been sending us happy thoughts."

There has been no official word on when the baby might make its appearance, but showbiz insiders are touting September as the likely month.
