Following a 25-year marriage, the legal filing comes after the couple split in May just days before the action star/politician stunned the world by confessing he had fathered a lovechild with a maid at the family home over a decade ago.
She's kept her silence ever since news broke of her affair with the former California Governor, but now Arnold Schwarzenegger's mistress, Mildred Baena, is speaking out to tell her side of the story.
In an interview with Hello! magazine, the Guatemala-born housekeeper explained that Maria Shriver had showed some suspicion about her 13-year-old son's parentage, before finally asking her "point blank" who the father was.
His relationship with her has cost him in both his personal and professional life, but that isn't stopping Arnold Scwarzenegger from coming to the aid of his mistress Mildred Baena.
As a source reported to RadarOnline, the former California Governor is still financially and emotionally supporting Baena, as they explained, "Arnold has been very supportive of Mildred throughout all of this."
The estranged couple were both spotted out and about in the posh California town - as Arnold took a midday cruise on his motorcycle while Maria did some shopping with their son Christopher (sans her wedding ring).
