Shauna Sand cheated on Lorenzo with A.J.?

I really don't know if this is true but the Star Magazine reports that Shauna Sand cheated on her former husband Lorenzo Lamas with his son A.J. when they were married.

A source told Star that the reason the couple split when they did was because Lorenzo found out Shauna “was sleeping with A.J. Lamas, his then-18-year-old son!”
The source dished: “Shauna came on to A.J. It was the ultimate betrayal. Lorenzo had no idea; he was in the dark about the whole thing. He thought Shauna was acting like a mom to A.J. He had no clue that she was his son’s lover!”

The source also added that the affair went on for months before Lorenzo filed for divorce from the former Playboy model.
