Arlene Dahl, mother of “Renegade” star Lorenzo Lamas, says her son’s bitter headline-making marital split from his Playboy Playmate wife Shauna has broken her heart.

“I am really shocked,” a saddened Arlene told The ENQUIRER in an exclusive interview. “I can’t believe this is happening. Theirs was such a beautiful love story. To have it all come to this is just so sad.”

Lorenzo, 44, and Shauna, 31, were married in April of 1996 in a romantic ceremony at Arlene’s palatial New York country home. Arlene, a legendary actress and famed astrologer, helped the couple select a wedding date so their marriage would have the greatest chance of success.

But after 61¼2 years together and the births of daughters Alexandra, 4, Victoria, 3, and Isabella, 20 months, the two are calling it quits.

In court documents filed on October 9, the actor charges his wife with physically abusing him and being an unfit mother. He’s asking for custody of the children and wants Shauna booted from the family residence. He also requested a restraining order against Shauna.

Shauna has responded with documents denying she has been abusive and charging that Lorenzo pressed her to become a stripper and an escort to bring money into the household, and that he hit their daughter Victoria, and made fun of her lisp.

“I can’t believe that both of them have to live through this nightmare,” said a sorrowful Arlene. “Their girls are so sweet — so wonderful.

“I love them both, but of course Lorenzo is my son. It’s just so sad.”
