If there's one person on the rock world who is the least deserving of anyone's respect, it's Sharon Osbourne.

Simply put, the wife of Black Sabbath vocalist Ozzy Osbourne is a bitch of the first degree.

While she may now be the star of X Factor and other lame reality/TV talk shows, her negative influence in the rock world shames her and removes any credit she should have.

Who else but a total, greedy fool would have two of the finest hard rock albums ever (Ozzy Osbourne's Blizzard of Ozz and Diary of Madman) featuring the late, great guitarist Randy Rhoads, re-recorded with new bass and drum parts after losing a songwriting credit lawsuit?

Sharon.

The idea being if the albums were recorded again, original bassist Bob Daisley and drummer Lee Kerslake wouldn't get future royalties for the songwriting they did on the records, but never originally got credit for (which led to a 1986 lawsuit against Jet records, owned by Sharon's father, Don Arden - won by Daisley and Kerslake).

So Sharon decided (she claimed it was Ozzy's decision, which he totally disputes in his autobiography) to redo the bass and drums using then Ozzy bassist and current Metallica four-stringer Robert Trujillo and drummer Mike Bordin. The albums were released again in 2002. It was blasphemy.

Naturally fans went ballistic at the move and, in 2011, a 30-year anniversary of the records was released with the original recordings.

Sharon became Ozzy's manager in 1981, right around the release of Diary and then they were married in 1982, upon when she basically starting telling Ozzy what to do, when to do it and how high to jump. For some great insight into the recording of Blizzard and Diary plus his thoughts on Sharon Ozbourne, check out Bob Daisley's recounting of those days.

And in keeping with being the ultimate shyster, she lied to former Ozzy Guitarist Jake E. Lee when he joined Ozzy to record 1983's Bark at the Moon.

According to Lee, he was promised credit for helping write on the album, but as soon as he'd finished the last track, Sharon offered him a contract that stated Ozzy wrote everything and would get all the publishing royalties.

Here's what Lee said on Eddie Trunk's show, talking about the contract: "And I looked at it. I’m looking at Sharon, and I said, ‘This is not what you told me before.’ And she says, ‘No, it isn’t.’

"‘Why do you think I’m gonna sign it?’" said Lee.

"‘Because if you don’t, we’ll give you a plane ticket, you go back home and you stand in line and you sue us. In the meantime, we have all your tracks, we’ll get another guitar player, he’ll redo your tracks, and you’ll have nothing'," replied Sharon.

Wow.

Sharon Osbourne Messed with Iron Maiden

Sharon easily took her bitchy self to new heights during the final Ozzfest show of 2005 at Glen Helen in California.

On that day, after Iron Maiden vocalist Bruce Dickinson slagged the corporate crowd in the front rows and Ozzy's use of a teleprompter, Sharon admittedly ordered the Maiden P.A. system to be cut (three times) during their set, and then had members of Maiden pelted with eggs and ice.

Sharon finally admitted she was responsible, arguing "(Dickison) didn't realize who he is messing with", adding he got what he deserved and from there, one of rock's biggest feuds began.

Why is Bill Ward Not Part of Black Sabbath Reunion?

Lastly when you look at Sharon Osbourne, you need think critically about why original Black Sabbath drummer Bill Ward is not part of the ongoing Sabbath reunion and final tour.

No doubt Ward wanted to play on the 13 record, then play the tour. But, according to him, he was never offered equal compensation back in 2012 when the ball got rolling to cap Sabbath's distinguished career.

At the time, the drummer was presented with a take-it-or-leave-it "unsignable contract", which he did not sign. Now who was the one behind the scenes managing Black Sabbath's affairs? You guessed it - Sharon Osbourne, even though she's not Black Sabbath's de facto manager, she still has a huge say in the goings on of the band.

And what about all the social media hype surrounding Sabbath's The End Tour - where all the old band promo pictures posted on Facebook had Ward's image cropped out, so newbie Black Sabbath fans might well think they were a three-piece band of Ozzy, guitarist Tony Iommi and bassist Geezer Butler. How can you show old pictures of one of the greatest hard rock bands in the world with the drummer cropped out? Insane.

It's just another episode in Sharon Osbourne's cache of bitchy moves.
