Maria Shriver Knew About Arnold Schwarzenegger's Infidelity with Mildred Baena?

With all of Arnold Schwarzenegger's secrets, it's hard to believe his wife of 25 years, Maria Shriver, was unaware of his infidelity which led to a child out of wedlock. After all, Maria was an investigative journalist for years. So when did the mother of four really find out about Arnold's indiscretions?

According to RadarOnline, via PopEater, Maria has growing suspicions about who housekeeper Mildred Patricia Baena's son's father was, and asked if Arnold was her now-13-year-old son's father.

Allegedly, Patty confessed and then Arnold admitted it to be true when his wife confronted him.

"Maria has suspected this for a long time and she asked the housekeeper," a source told RadarOnline. After Patty confessed, "Maria then went to Arnold and he confessed."

In the end, Maria learned the truth for herself, and Patty allegedly resigned in January "without animosity."

The former California governor admitted he had fathered an illegitimate child with a household staffer on Monday. More details about the scandal have been unraveling and reports of his mistress and son have been revealed.

Maria has reportedly hired top divorce lawyer Laura Wasser.
