But the couple's relationship has not hit a flat note - rather they have delayed their nuptials because Murphy is pregnant, rumoured to be expecting twins.

It's the latest exciting chapter to the couple's fairytale romance. They had intended to marry in a historic castle outside Paris in June.

Izambard met Murphy - his Australian record company publicist - when he was touring Oz with his mega-selling operatic group Il Divo in October 2005.

They had a long-distance relationship until Murphy quit her job with Sony BMG in July 2006 and moved to Europe to be with the singer.
