Pierfilippo told the Independent that his dad missing his big day is "absolutely not" a problem and that the family finds the whole thing a bit funny. Plus, since Pierfilippo and his soon-to-be wife already have two kids together, strict Catholic Fabio only considers the wedding a "formalizing" ceremony anyway.
All that aside, his son isn't paying him £6 million a year, so it seems Pierfilippo's overdue formalizing thing automatically comes a distant second to anything that does.
