Father-of-six Rod Stewart is in seventh heaven - his wife Penny Lancaster is pregnant again.

The rock legend, 65, is already dad to five kids - Kimberly, Sean, Ruby, Renee, Liam - with three different women, as well as four-year-old Alistair, with Lancaster.

And Stewart, who has spoken of his desire for another child, is celebrating again after learning he is to become a father once more.

In a statement, a rep for the singer says, "Penny and Rod were lucky enough to be celebrating more than just their third wedding anniversary in June, as the news came that Penny was pregnant with their second child.

"We were thrilled and delighted to be able to tell Alastair that he was going to be the big brother to a little baby, expected just before Mummy's 40th birthday."

The baby is due in March. The pair wed in 2007.
