This is the ultimate case of betrayal. For the past 13 years, Rogelio Baena wrongfully assumed that the young lad born to his then-wife Mildred “Patty” Baena was his biological son.  It wasn’t until about a week ago, when Arnold Schwarzenegger announced that he had fathered a love child with a household staff member (Midlred), that Rogelio discovered the shocking and heartbreaking truth.

Speaking on the painful revelation, 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.”

In the interview which aired this past Tuesday, Rogelio says he has a message for the boy:

“I am your father. That’s all.”

According to divorce papers, Rogelio and Mildred – married for 10 years – split in 1997 just weeks after the child’s birth, and that Mildred filed for divorce in 2008.

SMH. This one would’ve been the perfect segment on “Maury”.
