Shauna Sand is moving up a few notches on the skank-o-meter after reports state she slept with Lorenzo Lamas' son A.J.

“He thought Shauna was acting like a mom to A.J. He had no clue that she was his son’s lover!”

Lorenzo filed for divorce in 2002, months after the romance between Sand and his son reportedly heated up.

Lorenzo thought she was acting like a mom to A.J.? What, a mother that pokes her stepkid on the side? Now that's totally forbidden territory! Not to mention it's just gross to sleep with your husband's son, even if he's from a previous relationship. Shauna is a dirty girl.
