He's finally here! Shayne Lamas and her husband, Nik Richie, have welcomed their second child together. Lamas' stepmom, Shawna Craig, helped as the couple's surrogate.

The proud dad confirmed the news via Instagram earlier this month. "Shayne and I are happy to announce the birth of our son Lyon Lamas-Richie," the founder wrote on Saturday, July 4.

Lamas, 29, also shared the news with a cute video of the couple's 3-year-old daughter, Press, spinning in a chair.

"She must be bored being cooped up in the house all day," the Season 12 Bachelor contestant captioned the Instagram clip on July 14. "@presslamas brothers eat, sleep, nap schedule has put a short damper on her thrilling life."

Lamas and Richie's son "arrived via natural water birth" on the Fourth of July at 6 pounds, 4 ounces, the couple told Closer magazine. "Everyone is healthy and happy." (Craig and Lamas' dad, actor Lorenzo Lamas, wed in April 2011. Craig, 29, stepped in after Shayne had a miscarriage in February 2014.)

"Shawna's not just my stepmother. She's like a soul sister," Shayne told Closer in February. "She's an angel that blessed my whole family, including my father."
