Rod Stewart and his third wife Penny Lancaster are expecting another child, PEOPLE reported on August 9. The couple told the magazine that “We were thrilled and delighted to be able to tell (four-year-old son) Alastair that he was going to be the big brother to a little baby, expected just before Mummy’s 40′s birthday.” There is no news yet of the baby’s sex.

This will be the seventh child for the rock star, as he also has five other children from previous relationships. The news comes after Stewart told the British press last year that he wanted one more child.

Stewart has said he enjoys fatherhood, adding that Alastair is a “sweet kid.” The 65-year-old singer married the 39-year-old Lancaster in Portofino, Italy in 2007, a year after Alastair was born.
