Ozzy Osbourne gained fame as the lead singer of Black Sabbath, a band known for dark, occult-themed imagery and lyrics. While much of it was theatrical “shock rock,” Ozzy himself has said in interviews that he did not actually practice Satanism. In fact, some Black Sabbath songs (e.g., "After Forever") were openly critical of rejecting God. However, the band did intentionally use satanic imagery and themes to provoke and sell records.
So while Ozzy may not have been an actual practicing devil worshiper, he definitely portrayed darkness and occult imagery for fame and money—which is spiritually dangerous in itself (Ephesians 5:11).

No. Pretending to worship Satan is still sin. Scripture is clear that God looks at the heart and the actions, not just the intention behind them:

• “Abstain from all appearance of evil.” (1 Thessalonians 5:22)

• “Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils.” (1 Corinthians 10:21)

• “What concord hath Christ with Belial? or what part hath he that believeth with an infidel?” (2 Corinthians 6:15)

Even if it’s “just for show” or “just for money,” it is still aligning yourself with darkness and could mislead others. Jesus said:
“Whosoever shall deny me before men, him will I also deny before my Father which is in heaven.” (Matthew 10:33)

In short: pretending to worship Satan for profit is incompatible with following Christ.

Can you be a Christian and pretend to worship the devil for money?
