It was such a cringeworthy moment that it was almost painful for everyone involved, but Ozzy Osbourne and Sharon Osbourne were forced to put their game faces on and pretend all was well as they re-united briefly in a Hollywood press conference to announce Ozzfest Meets Knotfest yesterday (May 12th 2016).

Sharon and Ozzy OsbourneThings still looked tense between Sharon and Ozzy Osbourne

Unfortunately, Sharon is still acting as husband Ozzy's manager despite their very recent break-up, so she deserves a huge amount of respect for bravely attending the latest press announcement despite knowing that questions would be raised about their future together as a couple. Needless to say, it was as awkward as you could have imagined it would be.

Sharon was all smiles as she welcomed her estranged husband to the stage to a rousing cheer from the audience, but she had her limits. Ozzy gave her a little hug (as best he could) upon his appearance, but she did not soften; clearly it's one thing to be referring to Ozzy as 'a friend of mine' but another to consent to physical contact.

The pair were officially announcing Ozzfest Meets Knotfest with Corey Taylor of Slipknot; a two-day festival headlined by Black Sabbath and Slipknot. 'She was not into him hugging her at all', a source told Us Magazine. '[During the photocall] Ozzy kept trying to put his arm around her.'

The publication also claimed recently that Sharon found about Ozzy's alleged affair with celebrity hair stylist Michelle Pugh by 'searching through [his] emails', which we all know ended up in a fiery confrontation that saw Sharon kick her husband out of their $10 million Beverly Hills home.

They've been married for nearly 34 years with three grown-up kids and their relationship has always been tempestuous. However, reports fear that this may be the last straw for one of showbiz's most electric couples - though Sharon admitted on 'The Talk' that she didn't know what the future held. 'I honestly at this point today, have no idea what I'm going to be doing for the rest of my life', she said, though confessed, 'I love Ozzy dearly. He's given me unbelievable life. He's given me three gorgeous children and I love him.'

The feeling's mutual; Ozzy opened up about the split to Entertainment Tonight: 'She's my right arm. She's everything for me', he said. 'She's great.' But coming back from something like this isn't going to be easy for either of them. 'This is the first long-time affair Sharon has found out about', a source told ET. 'This is an emotional affair - it wasn't just a one-time hook-up. There are feelings there between Ozzy and this woman. This is a double life he's been leading.'

Ozzy's friends did use the press conference opportunity to try and get the pair back together, however. 'Backstage the guys from Slipknot, guitarist Zakk Wylde and Anthrax's Scott Ian all were talking to Sharon and laid it out to her that she and Ozzy are perfect for each other and whatever their problems are that they should just get over them', a source told Hollywood Life. 'Ozzy apparently loved it and hopes his buddies talked some sense into her and Sharon appreciated the concern.'

Before we get our hopes up too much though, it's worth noting that Sharon isn't famous for doing what other people think she should do.
