The couple split in May after almost 33 years of marriage amid claims the Black Sabbath rocker had been unfaithful, but insiders claim they are now stronger than ever thanks to joint therapy sessions.
The source told Us Weekly magazine: ''They've fallen in love again.''
Sharon and Ozzy's daughter Kelly Osbourne recently revealed the couple were back together because their union is strong enough to withstand an affair - though she thinks her dad was ''stupid'' for allegedly cheating on the 63-year-old TV star with hairdresser Michelle Pugh.
She said: ''My mum and dad are together right now. I will never not be good with my dad. That does not mean that I think what he did wasn't f***ing stupid, but that's between him and I. I'm a daddy's girl. I love my dad.''
Meanwhile, it was previously claimed that Ozzy is willing to go to any lengths necessary to rebuild his marriage.
A source shared: ''He wants his family back. The Osbournes have been through thick and thin together and have stayed together through it all. This is putting them all through a really horrible time.''
And Sharon recently praised her daughter Kelly for posting Michelle's phone number online and thought it was incredibly ''funny''.
Speaking about Kelly's tweet which read ''Anyone looking for cheap chunky LOW-lights a blow out and a blowjob call *********** (sic)'', she said: ''Oh, Kelly has the best sense of humour ever. And you know what? In cases like this, what can you do but laugh? What are you gonna do - be angry with her because she loves her mom and dad and she wants us to be together? She loves us. She can do what she wants, because she's an adult. You have to laugh. She is just so funny. I'm always proud of my girl.''
And Sharon previously admitted she is the ''strongest'' she's ever been.
She said at the time: ''I think I'm the strongest I've ever been right now, with everything that's going on in my life. I feel it.''
