Sharon and Ozzy Osbourne have moved out of their Los Angeles home and are living apart, according to The Sun. The couple, who have been married for 31 years, haven't seen each other for three weeks since they moved out the property but are thought to still be in a relationship.

Sharon and Ozzy are known for their rows and fiery relationship, though it appeared to work for them - or did it on-screen, in their hit MTV show. However, the fights appear to have taken their toll and Sharon is staying in a hotel until her new house in Beverly Hills is renovated, while Ozzy is renting a property two miles away. "They are living at different addresses and are not spending any time together. They row a lot," a source said, "They aren't acting like husband and wife. It is unusual to not even have dinner together when both of them are five minutes apart."

A friend of the couple also told the paper "Sharon and Ozzy have had plenty of opportunities to meet up but haven't spent any time together at all." The couple have been spotted without their wedding rings at numerous events this year, and Sharon recently alluded to the personal problems by tweeting about having a "really tough year."

Sharon is reportedly re-joining The X Factor panel this year, though Noel Gallagher remains number-one on Simon Cowell's wish-list. Nicole Scheringer is a doubt, though Louis Walsh and Gary Barlow should be back.
