Where is Mildred "Patty" Baena?

The housekeeper and assistant for Arnold Scwharzenegger and Maria Shriver's family retired after 20 years earlier this year– and became a household name on Wednesday, when multiple outlets identified her as the mother of Schwarzenegger's illegitimate son, said to be 13 years old.

Reporters quickly descended upon Baena's home in suburban Bakersfield, Calif.; unsurprisingly, the alleged mistress, 50, and her son were nowhere to be found. The Associated Press says that Baena purchased the Bakersfield house a year ago — and that Schwarzenegger was assisting with the down payment on the $268,000 property.

Neighbors told the Associated Press that Baena's 13-year-old son was a polite boy frequently seen walking his white poodle, Sugar, swimming in his backyard pool, and playing basketball.

His mom, however was more scarce: Prior to her retirement 2 1/2 months ago, neighbors said Baena spent most of her time working for the Schwarzenegger-Shriver brood 100 miles away, keeping an L.A. apartment near their Brentwood estate. Regardless, Baena and family were friendly and took tidy care of their home.

Baena's MySpace page features a photo of her son — which bears a strong resemblance to the actor-politician. "I would see the resemblance," neighbor Marilyn Steelman said.

Also scrutinized: the birth certificate for Baena's son, who was born the same week as Christopher Schwarzenegger, the star couple's youngest. Baena's ex-husband is listed as the father, and Baena's birthplace was Guatemala.

When she purchased the house, Baena was listed as "single" on the deed, but neighbors noted that a man who they presumed to be her husband also lived with them.

How is the former Terminator doing?

"It's been very, very hard for him," one source close to the former governor told the Associated Press. "He's embarrassed. He's not focused on what steps he needs to take for himself, but the steps he needs to take for his family."

In addition to young Christopher, Schwarzenegger and Shriver have four kids: Katherine, 21, Christina, 19, and Patrick, 17.
