Elton John and his longtime partner David Furnish are expecting a sibling for their son Zachary, The Daily reports.

The couple welcomed their first child via surrogate in 2010, and the same surrogate is now in her first trimester of pregnancy with their second child. Interestingly, the unidentified woman, who was found through the Center for Surrogate Parenting in Encino, also carried Kelsey and Camille Grammer's two children.

"I'd love to have more children. I want [Zachary] to have a brother or a sister to go to school with him, and so that he can have someone to play with. It's going to be heartbreaking for him to grow up and realize he hasn't got a mummy. But he's so happy. I've never seen a more contented child. And you have never seen two more contented people as David and I," the Grammy winner revealed of his motivation to add to his family.

Congrats to the happy dads!
