Neighbors say she, and her son fathered by Schwarzenegger, live in a Bakersfield home with her three other children. A neighbor said the family is always cordial - especially the boy.
"This young man is just at the top end of being polite and being very cordial. He is somebody you want to be around," said a neighbor.
According to public records, Baena purchased the home last June around the same time she says she retired as the Schwarzengger's family housekeeper and assistant.Real estate records at the county assessor's office make no mention of Schwarzenegger's name.
Schwarzenegger, who recently separated with his wife, Kennedy family heiress and former network journalist Maria Shriver, acknowledged Monday that he fathered a child with a former employee more than a decade ago.
Schwarzenegger has said Shriver didn't learn the child was his until he told her after leaving the governor's office in January.
The birth certificate for the Bakersfield woman's son shows he was born the same week as Schwarzenegger and Shriver's youngest son, Christopher Schwarzenegger.
Shriver, who has declined to discuss the matter since issuing a brief statement on Monday, made an appearance Monday at a taping of Oprah Winfrey's farewell show, telling the talk show host she has "given me love, support, wisdom and most of all the truth."
