Twitter is abuzz with reports that one of the longest marriages in celebland - that of Sharon and Ozzy Osbourne - has crumbled after 31 years.

Sharon Osbourne was spotted moving into a new Beverly Hills home just days before she was seen out without her wedding ring on.

The Reality TV couple have apparently been living apart for three weeks, and reports say they are now going their separate ways. Update: Ozzy has released a statement on his marriage and drug problems, check it out here.

Have a look at their relationship through the years - from mullets to MTV reality shows, and from gastric bands to great PDAs:

Sharon and Ozzy met when she was just 18-years-old and working for her father, Don Arden, who was then managing Black Sabbath.

When Ozzy was sacked from the band in 1979, Sharon started to date him and took over his management as a solo artist.

Three years later in 1982, Ozzy and Sharon tied the knot in Maui, Hawaii. They have three children together - Aimee, Kelly and Jack.

The family - minus Aimee - starred in MTV reality TV show The Osbournes, which first aired in 2002.

Two years later Sharon joined The X Factor panel in the UK, where she developed a very public rivalry with fellow judge Dannii Minogue.

After she left the show in 2007 she joined the America’s Got Talent panel, before landing her own talkshow.

In 2005 Ozzy admitted: ‘To be honest, I was a little bit jealous at first. It’s not jealousy so much; I think my ego was damaged a little, but now I don’t care as long as she’s having fun and doing what she wants to do.’

The couple are said now to be worth £110?million.

Sharon recently Tweeted alluding to difficulties in her life, saying: "I've had a really tough yr & I ask myself...how can I get up every day & smile."
