from www.popeater.com – Scenario: A man divorces his wife after discovering she was having an affair … with his son. It’s a story so scandalous, it could’ve been ripped right out of a script from a soap like ‘The Bold and the Beautiful.’ Fitting then, that one of the former star’s of that show has reportedly lived that icky scene.

Star magazine is reporting that Lorenzo Lamas left his fourth wife, Playboy model Shauna Sand, after it came to light she was sleeping with his then 18-year-old son, AJ. A friend of the actor called it the “ultimate betrayal” from the model.

“Lorenzo had no idea; he was in the dark about the whole thing,” the friend said. “He thought Shauna was acting like a mom to A.J., he had no clue that she was his son’s lover!”

Lamas married the former Playmate of the Month in 1996 and they had three daughters together. He filed for divorce in 2002. The one-time ‘Falcon Crest’ star has not re-married.

According to reports, Lamas is currently filming a reality show revolved around his family for E!, where he will supposedly address the scandal.
