Sharon and Ozzy Osbourne have sparked speculation their marriage is going through a tough path.

The TV star and Black Sabbath rocker have been married for 30 years and have three children together. It has been claimed they are currently living apart after they both moved out of their mansion.

“They are living at different addresses and are not spending any time together. They row a lot,” an insider told British newspaper The Sun

“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.”

It has been suggested the pair have not spent time with each other for the last three weeks.

At the moment, Sharon is living at the Beverly Hills Hotel while Ozzy has a rented property.

“Sharon and Ozzy have had plenty of opportunities to meet up but haven't spent any time together at all,” another source claimed.

The pair have also been seen without their wedding rings.

Last week, their daughter Kelly hinted the family was having issues with a post on a social networking website.

“Why does every family in the world have that 1 member that will never get it and is completely ignorant to life in general?” she wrote on Twitter.

Sharon also suggested things haven’t been easy while talking to a fan on the site.

“I've had a really tough yr & I ask myself the same question, how can I get up every day & smile (sic),” she wrote.
