Ex-BAYWATCH beauty DONNA D’ERRICO’s new life of Biblical proportions!  

 FORMER “Bay­watch” dazzler Donna D’Errico, best remembered for her heav­enly body, says she’s turned her life over to God.

The 44-year-old former Play­mate of the Month has become a devout Catholic and confesses she “made mistakes and choices in my past that I wouldn’t make today.

“That’s a chapter in my life that I’ve closed the door on. It’s not who I am today.”

Donna, who starred on “Bay­watch” and “Baywatch Nights” in the 1990s, turned her back on the Hollywood lifestyle after her divorce from rocker Nikki Sixx in 2007.

Now,  she attends Mass on Sun­days and prays the Rosary every night with her son Rhyan, 19, and daughter Frankie Jean, 12.

“Donna’s faith is every­thing to her,” an insider told The ENQUIRER. “She’s a shining example of how belief in God has changed the course of a life.”

Donna’s amazing leap of faith included climbing Turkey’s Mount Ararat last summer in search of the remains of Noah’s Ark. She had a brush with death dur­ing a hiking accident that left her with a busted-up face and a cut on her leg.

“That experience was a turning point and gave Donna real perspective on what’s impor­tant in life,” said the source.

Incredibly, the beauty wants to return to Turkey to renew her search for Noah’s Ark. She also plans to visit the house where some believe the Virgin Mary spent her final days.

But she has no desire for mate­rial things. “I have everything I need,” said Donna. “I have my children, my health and my pets. I have my faith in God.”
