Ozzy Osbourne is hoping his son JACK has included footage showing him in "a bad mood" in his new documentary - so fans can see the rocker's real personality.
The 24 year old has filmed his father for new project Wreckage Of My Past, but he's refusing to show the legendary Black Sabbath singer the film until it's completed.
And Ozzy is just praying Jack has included enough footage to give his fans an insight into his life - good or bad.
He says, "I said to him: 'Jack, it can't be how wonderful I am all the time because I'm not that way all the time. Everybody wakes up in a bad mood sometimes.'
"I'm hoping he's put a bit of sweet and sour in there. For every good thing there's a bad thing, you know. When I was drinking I don't suppose I was Mr Charming."
