Mildred Patty Baena Picture

Mildred Patricia Baena is the mistress and mother of Arnold Schwarzenegger's out-of-wedlock child. She worked as an assistant in his house for over 20 years.

Arnold has four children with Maria Shriver, his now-estranged wife of more than 25 years. Mildred Baena, also known as Patty Baena, has three of her own.

It's not clear how in the heck Schwarzenegger kept this secret for over 14 years, but it only came to light in May 2011 after he and Maria Shriver separated.
