California-A spokesman for Sharon and Ozzy Osbourne has fuelled rumours of a split by revealing the rocker is not currently staying at their marital home.

Multiple reports suggest rock matriarch Sharon Osbourne , 63, has kicked theBlack Sabbath frontman, 67, out of their California mansion after more than 33 years of marriage. Sources tell British newspaper The Sun Sharon and Ozzy became engaged in a heated argument last week amid allegations of the musician’s infidelity.

She is said to have confronted him with alleged proof he cheated on her with a 45-year-old celebrity hairdresser named Michelle Pugh. The insider claims Sharon went “ballistic” and insisted she had suspected he was having an affair for quite some time.

“People are wondering whether Sharon went through Ozzy’s phone before accusing him,” a source said. “She has done that before but in the past she was checking if he’d been using drugs. Ozzy was extremely sheepish and admitted being close to Michelle. It is likely Sharon has discovered calls and possibly meetings.”

Ozzy is now reportedly staying at The Beverly Hills Hotel. The couple’s representative, Gary Farrow, appeared to confirm to The Mirror that the Osbournes’ marriage is on the rocks, simply noting: “At this time Ozzy is not at the marital home.”

Meanwhile, hairstylist Michelle has taken time off from her place of work, the Meche Salon, to deal with a “personal emergency”, reports The Mirror.

It’s not the first time Sharon and Ozzy have separated. Back in 2013, Sharon admitted she was considering divorcing Ozzy after he relapsed on drink and drugs. The stars, who share adult children Aimee, Kelly and Jack, subsequently reunited.
