The Lamb of God singer was detained in Prague last month amid accusations he pushed a fan off stage at a concert in the city in May 2010. The man reportedly died of a brain haemorrhage two weeks later.
Blythe recently posted bail, but remains behind bars as officials move to organise his release.
His bandmates launched a fundraising drive to pay his legal bills and Slash urged fans to back the fund - and now the Osbournes have voiced their support for Blythe.
In a post on her Twitter page, Sharon Osbourne writes: "Please support former Ozzfest member Randy Blythe from Lamb of God. Free Randy Blythe," while her husband Ozzy re-tweeted the message on his own account.
