Sharon Osbourne has praised her son Jack for influencing Ozzy Osbourne to seek help for his lifelong addiction to drugs and alcohol.
Jack, like his father has battled with alcohol abuse for many years, and has been sober and focusing on his career in TV
The Black Sabbath frontman's battle with alcohol and illegal substances has been well documented over the years, but it was only when Jack checked into a child psychiatric ward to deal with his personal issues in 2003 that the Black Sabbath frontman became serious about confronting his own problems.
Speaking in candid new documentary GOD Bless Ozzy Osbourne, which was produced by Jack, Sharon says, "Jack getting sober was... really his big turning point... Jack was dealing with life sober for the first time."
The 62-year-old singer has spent the past few years completely sober after vowing to clean up his act for the sake of his loved ones and his dedication to the cause has stunned even his closest relatives.
The Osbournes' eldest daughter, Aimee, says, "He's really blown us away... It really seems like he's come through the other side."
Kelly Osbourne reveals she is proud of her dad for sticking to his promise: "I spent 19 years of my life praying he was the father I have today. Not many people can say that."
And Sharon has echoed her daughters' sentiments, adding, "He works really hard for his sobriety and he deserves it."
GOD Bless Ozzy Osbourne premiered at the Tribeca Film Festival in New York on Sunday.
