Amber, 37, and Andrew, 40, met when the actor played his now-wife’s love interest on Greek. The couple began dating and wed in December 2014.

“It was the most magical night of my life,” Stevens West told PEOPLE following the ceremony. “I wish I could rewind and play it again, but I’m so looking forward to our future together.”

The two welcomed their daughter Ava in October 2018, telling PEOPLE at the time that they were over the moon to add a little one to their family.

“We feel like we’ve been waiting our entire lives to meet our daughter, Ava,” Amber and Andrew told PEOPLE. “Now that she’s here, we’re completely obsessed. She’s already introduced a new and unique type of love into our lives and we’re so excited to see what else she will show us and teach us in the years to come.”

Ava’s name was suggested by one of her grandmothers early in the pregnancy, and both new parents were immediately enamored with the moniker. Her middle name, Laverne, was chosen in honor of two great-grandmothers — one on either side of the family.

In August 2021, they welcomed their second daughter together, Winona Marie, who goes by Winnie. The couple shared the exciting news in an Instagram post.

"Introducing Winona Marie West! 🌷 & 📸 by @nuleafdesign 👶🏽 by me and @andrewjwest but mostly me," Amber wrote in her caption.

In an interview with PEOPLE ahead of welcoming Winnie, Amber and Andrew shared that their daughter Ava couldn't wait for her new sibling to be born. "[She] talks about it every day, this person coming and what she's going to do with them. She kisses my belly, gives me hugs," Amber said.
