In a stunning revelation, Arnold Schwarzenegger revealed that he had fathered a child from an affair he had over a decade ago, but according to the testimony of one woman, this isn't the first time the actor-turned-politician has cheated.

A woman has alleged she was just one of many mistresses that shattered Arnold Schwarzenegger's 25-year marriage.

Schwarzenegger denies an affair with Gigi Goyette, but the 52-year-old woman has said: There were so many other women. About 13 have come out of the woodwork, according to the Daily Mail.

She claims she met Schwarzenegger in 1975, when she was a 16-year-old child actress on Little House On The Prairie.

Gigi claims that she slept with the star once in that year but did not see him again until 1989, during which year they began their alleged fling - three years after Schwarzenegger married Shriver, 55.

I don't think I had anything to do with the break-up of his marriage, she told the DailyMirror  earlier.

Schwarzenegger announced an apology to his wife, family, and friends after leaving the governor's office earlier this year.  

After leaving the governor's office I told my wife about this event, which occurred over a decade ago.  I understand and deserve the feelings of anger and disappointment among my friends and family. There are no excuses and I take full responsibility for the hurt I have caused, said the former California governor.

The acknowledgement of paternity has apparently prompted his wife, Maria Shriver, to leave the couple's home before officially announcing their plans for divorce to the public.
