I recently heard about this too. Seems he got "saved" abouta year ago I believe. But it seems this is not the first time he has "converted" to a religion. Previous times he left the beliefs behind. He, at one point, became a Rastafarian and rebranded himself Snoop Lion.
I heard a new song, it's lyrics were questionable. Not too surprising for a newer believer. He's not the first famous musical artist to become saved and continue making music.
