Arnold Schwarzenegger's sexual relationship with his longtime housekeeper wasn't just a one-time fling.

The Governator and Mildred 'Patty' Baena maintained an ongoing sexual relationship, Breaking Celebrity News has learned in a blockbuster joint investigation with Star magazine.

Breaking Celebrity News and Star were first to reveal Baena's identity, with details that conflict the muscleman's official version of how the love child scandal was dragged into the light after 14 years.

"Arnold and the housekeeper had a sexual relationship that stretched over years," a source close to the woman told Breaking Celebrity News.

"This wasn't a case of Arnold being unfaithful just once. Far from it.

"This was a sexual relationship that played out right in front of Maria and in her own house for years."
