Sharon Osbourne’s spokesperson has denied rumours that she and husband Ozzy have separated.

The Sun reported earlier on Sunday that Sharon – who is being tipped to returb to The X Factor judging panel – was living apart from Ozzy, staying in a hotel two miles from their Los Angeles home.

However Sharon’s representative has claimed that the separation is simply due to the pair’s busy work schedules.

“They’ve both got huge work commitments,” the spokesperson said. “She is at the hotel for work and he is starting his Black Sabbath tour.

“Of course they row but they are still together. Sharon and Ozzy have spent long periods of time apart before when she was working in the U.K. The marriage is not on the rocks.”

The paper had reported that the pair have not seen each other for three weeks – with Ozzy renting a property and Sharon living in a hotel while her home in Beverly Hills is renovated.

“A source had 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.”

The couple, whose relationship came under the spotlight in the hit reality show The Osbournes, have been married for 31 years.

Speculation is still rife that Sharon could be about to make her X Factor comeback – a move which would reunite her with fellow panellist Louis Walsh.
