According to British tabloid News of the World, the beauty icon will become a mother again at the end of the year. "They're in seventh heaven," the paper quoted a friend of Schiffer's, referring to the model and her British husband, Matthew Vaughn, who works as a movie producer. "They really want a sister for their son Caspar."

The 33-year-old's son was born in January 2003. Schiffer, who now lives in England and is currently staying at her residence on the Spanish island of Mallorca, has repeatedly said that she very much enjoys being a mum.

Caspar has already begun to follow in his mother's footsteps: Together with his mother, he has been on the cover of a German mail-order catalogue and stars in a commercial for a popular German chocolate bar for children.
