RadarOnline.com and Star Magazine broke the story, with TMZ and ABC News confirming.

Who is she?

According to ABC News, Baena, known as Patty, had worked for Schwarzenegger as an assistant and housekeeeper for more than 20 years.

Baena's adult daughter, Jacqueline Rozo, told The Associated Press her 50-year-old mother had worked for the former governor until recently but would not comment further.

According to RadarOnline.com, Baena threatened to go public with the news that she had given birth to Schwarzenegger's son, and that prompted the actor's public admission.

Baena, the boy and her three other children live in Bakersfield, Calif., about an hour north of Los Angeles. A neighbor told local station KABC that Baena's teenage son is "polite and very cordial, someone you want to be around."

A photo of the boy posted on Baena's MySpace page shows a fairly strong resemblance to Schwarzenegger, particularly when the former governor and movie star was younger.

Schwarzenegger and Maria Shriver jointly announced May 9 that they were splitting up after 25 years of marriage.  Shriver moved out of the family's Brentwood mansion earlier in the year after Schwarzenegger acknowledged the child is his, The Los Angeles Times reported Tuesday.
