Prince became a JW last year, though I imagine he is having trouble as many such performers do. He will not have a performance on Saturday night to make sure he makes it to the meeting the next day, as he did here in Kansas City. He took a taxi to the meeting. His recent decision to become a lounge singer in Vegas may be to get away from the demands and temptations of touring.
Michael Jackson left the witnesses because he couldn't maintain the life style a commitment to Christ requires. He now has the backing of Islam.
There are many movie actors and professional singers who are witnesses. One person of interest you should look up is the Actress who had her own police action TV show called "Get Christi Love".
No, see, it's possible for Prince to give the JW a bad name or bring with him a tarnished reputation. With Tom, it's the other way around. Scientology was the dirty partner. It brought all the junk into the relationship and turned him into the whack job he is now.
Jehovah's Witnesses go from house to house to share the "Good News" from the Scriptures; reportedly the entertainer Prince performs this ministry as a baptized Witness himself.
(Matthew 24:14) And this good news of the kingdom will be preached in all the inhabited earth for a witness to all the nations
(Luke 9:6) They went through the territory from village to village, declaring the good news
(Acts 5:42) Every day in the temple and from house to house they continued without letup teaching and declaring the good news about the Christ, Jesus.
By stark contrast with so-called "religious" activists, however, Jehovah's Witnesses note pointedly that biblical "good news" is not about such things as abortion or homosexuality or the death penalty or Iraq or pharmaceuticals or psychiatry. Individual Jehovah's Witnesses may have opinions on such issues, but they do not advocate for or against these issues as though it were a primary message from God.
Sadly, so-called "religious" activists distract from the real message of God and obfuscate the Bible's "Good News". These self-absorbed coreligionists focus so much attention of their human agendas that they ignore the godly teachings that can really help people.
Jehovah's Witnesses go from house to house to encourage and up build. Their work is to spread the "Good News", which is about the Kingdom of God, and the blessings the Messianic King Christ Jesus will bring.
(Luke 8:1) Journeying from city to city and from village to village, preaching and declaring the good news of the kingdom of God
(Acts 10:36) Declare to them the good news of peace through Jesus Christ
