There is no publicly available information regarding whether Justin Bieber's dad, Jeremy Bieber, is circumcised. Personal medical details like circumcision status are typically considered private and are not disclosed by individuals unless they choose to share that information.
Other than rumours, speculation and unverified sources, he has not publicly stated whether he has been circumcised or not. Justin Bieber was born in March of 1994 in Stratford, Ontario, and while circumcision was offered free of charge at this time, as low as 29% of baby boys in Ontario, Canada, were circumcised, so there is a chance that he is not circumcised but this is not conclusive. Also, why do you even care?
