Tommy Lee remembers a time Ozzy Osbourne's outrageous antics went too far even for him, when the Black Sabbath legend decorated the walls of the Motley Crue drummer's hotel room with a fistful of his own excrement.

Lee admits Osbourne's faeces mural may have been a "gesture of friendship", but it was one gift he could have lived without.

He recalls, "Ozzy took a c**p in my hotel room, right in the middle of the carpet, and then started painting the walls with his own s**t.

"Just when you think you've seen everything. I'm not the easily-shocked type but that episode had me reeling.

"Maybe, in some f**ked-up way, Ozzy meant it as a gesture of friendship."
