(Cover) - EN Showbiz - It has been claimed that the mother of Arnold Schwarzenegger's love child had threatened to reveal their affair last month.

Yesterday, the former Governor of California admitted he had fathered a child with another woman while married to Maria Shriver.

He explained the incident happened ten years ago and was the reason he and Maria recently announced their separation, although he did not reveal the name of the mother or the child.

However, RadarOnline, TMZ and Star magazine have identified the woman in question as being Mildred Patricia Baena, who is known as Patty.

According to sources, Mildred had been eager to reveal details of the affair last month when she had been released from her job working as a housekeeper for Arnold and his family around four weeks ago.

"Mildred was furious that the father of her 14-year-old son would callously fire her from her job after decades of loyal service," a confidante of Mildred's told RadarOnline.com.

"She admitted to friends how she finally wanted to tell the secret - that she had kept faithfully for 14 years - to the world."

Arnold and Maria married in 1986 and have four children; Katherine, 21, Christina, 19, Patrick, 17, and Christopher, 13. Maria released a statement yesterday admitting she is going through a "heartbreaking" period and asking for her and her children's privacy to be respected. (C) Cover Media
