The man who created the Backstreet Boys and N Sync is scheduled to be sentenced in Florida on four federal charges.
Lou Pearlman faces up to 25 years in prison and €623,000 in fines.
He pleaded guilty in March to two counts of conspiracy, money laundering and using false statements in a bankruptcy proceeding.
His is to be sentenced later.
Pearlman is most famous for piecing together boy bands in the 1990s that sold millions of records.
But prosecutors allege he conned investors and banks out of around €187m in a decades-long investment scam.
