This is truly a tight-knit family.

Shayne Lamas’ stepmom, Shawna Craig, is carrying her baby. At 29 years old, Lamas is a year older than her stepmother, who is acting as her surrogate.

“Shawna’s not just my stepmother, she’s like a soul sister,” Lamas said in the latest issue of Closer, which featured exclusive family portraits. “She’s an angel that blessed my whole family, including my father.”

Craig, 28, is the fifth wife of Shayne’s father, Lorenzo Lamas, who was on “The Bold and the Beautiful” from 2004 to 2006 and most famously starred in “Renegade.” 

Shayne and husband Nik Richie’s quest to have more children, after welcoming daughter Press Dahl three years ago, has been ongoing.

They lost their unborn baby boy in 2014 after she suffered a uterine rupture. As a result, the couple can no longer have children biologically.

Craig, who actually works at a fertility agency that helps couples (like Shayne and Richie) select egg donors and surrogates, decided to become a surrogate for her husband’s daughter.

“I’m ecstatic to be pregnant,” said Craig, who is due to give birth to a boy July 10. “It’s the best thing in the world.”

Recognizing how special their blended family is, Shayne admits the situation is not typical.

“Somebody else carrying your baby is weird,” she added. “But I lost my son, and now Shawna is carrying my son. I have been given the biggest blessing in the whole world and I will always be grateful.”

Shayne and Richie, who is the creator of TheDirty.com, quickly met and wed in April 2010 in a Las Vegas ceremony.
