Furnish, 49, said he and the 'Sacrifice' hitmaker, 65, are thinking about enlisting the help of a surrogate once more to give one-year-old son Zachary a little brother or sister, reported Contactmusic.
"I would like Zachary to have a sibling. It's something we talk about all the time. But in terms of when, where and how, nothing's decided yet. I think we are going to wait till this summer. Our life is always like a treadmill with Elton constantly working and touring," Furnish said.
John started dating Furnish, a former advertising executive and now filmmaker in 1993 and the couple became civil partners in 2005.
