The estranged husband of the woman identified as the mother of Arnold Schwarzenegger's out-of-wedlock son says he just learned the truth about the boy's parentage.
"One week ago," Rogelio Baena said when asked when he learned that he was not the child's biological father.
In an interview broadcast Tuesday, Baena told Entertainment Tonight's "Insider" that he was still committed to the child who he hasn't seen since last year.
"That's my son," he said. "I don't know what happened."
The Colombian also said he had no idea that his ex-wife Mildred Baena had had an affair with the former California governor, movie star and husband of Maria Shriver, a member of the Kennedy political dynasty.
"The Insider" also broadcast video Tuesday of Maria Shriver praising Mildred Baena at a 2001 celebration for one of Baena's relatives.
Rogelio Baena admitted he was angry about the news.
"I don't know if he's watched TV," he said in Spanish when asked if the child had found out about the scandal.

Shriver said she was proud of Baena for being a single, hard-working mother. Schwarzenegger can be heard echoing her praise, saying the housekeeper did "an incredible job."
