Baena, known to friends as Patty, was last spotted at her upscale Bakersfield, CA home Sunday, leaving out just days before the news of her scandalous affair with the former California governor broke.
RadarOnline.com and Star Magazine were first to report the identity of Baena, and the news came as a complete shock to the former maid's neighbors.
"We had absolutely no idea that she had any connection to Arnold Schwarzenegger," Baena's next door neighbor told RadarOnline.com.
"She's a nice lady but she keeps herself pretty much to herself.
"To say everyone is shocked by the news would be an understatement.
"We never saw Arnold at the house although I know he has visited Bakersfield several times in the past few years."
