MILDRED PATRICIA BAENA, also known as 'Patty Baena', has been revealed as the mother of Arnold Schwarzenegger's fifth child, reports TMZ.com. MILDRED PATRICIA BAENA, a housekeeper and assistant for the actor's family, gave birth to Schwarzenegger's son around 10 years ago.

Mildred worked closely with the family for more than 20 years, with her duties including cleaning, cooking and doing the laundry. Sources say Patty began to "pursue Arnold" in the late 1990's and soon became close to the 'Terminator' star. The insider reveals that Patty chose not to tell Schwarzenegger he was the father of her child until the boy was a toddler. Mildred, who made $1,200 a week working for the family, is now retired and lives in a comfortable 4 bedroom home close to Los Angeles. As well as her son with Schwarzenegger, she also has three other children. The actor released a statement on Monday (16th May 2011) admitting to fathering a child with another woman, but refused to name those involved. He recently split from his wife Maria Shriver after 25 years of marriage, saying he had only recently told her about his fifth child.

Arnold Schwarzenegger has four children with Shriver, 21-year-old Katherine, 19-year-old Christina, 16-year-old Patrick and 13-year-old Christopher.
