For the last 13 years, Rogelio Baena thought the boy born to his then-wife Mildred “Patty” Baena was his biological son.
It wasn’t until a week ago, when Arnold Schwarzenegger announced that he had fathered a love child with a household staff member, that Rogelio discovered the truth.
Breaking his silence, Rogelio tells Entertainment Tonight that the situation was a “betrayal” and that he had always considered Schwarzenegger – who employed Patty for 20 years – a “hero.”
