Clearly, there were fireworks between the two as they welcomed their first son, Augustus "Gus" Morgan, less than a year later.

The two lovebirds appeared to be happily in love at the season 10 premiere of Morgan's show The Walking Dead.

The couple welcomed their second child, daughter George Virginia, in February 2018, and Morgan played an integral role in her arrival.

"George started coming and the midwife moved aside. And I just went in and grabbed her by her little cheeks and had her out in 3 seconds," he said while on Jimmy Kimmel Live!.

As for her name, the proud father revealed the origin of the moniker: an episode of Bonanza titled "A Girl Named George."

"I loved the name and Hilarie loved the name. Gus is named after Augustus McCrae in Lonesome Dove. We got a weird western theme going on," he joked.

After a decade together, Burton and Morgan secretly tied the knot on Oct. 5, 2019, in an intimate ceremony in New York surrounded by friends, family and their two kids.

"We've lived as husband and wife for a decade. We've built a family, and a farm and found our community," the beaming bride wrote. "For years, publications have reported that we got married in 2014 or 2015 and that I've been married and divorced before. All untrue. But WE knew our truth. So it felt silly to try and correct anything."

For Valentine's Day in 2023, Burton reminisced about some of the small ways Morgan won her over, including embracing her friendship with one of her best pals.

"When I first started talking to my Valentine-for-life @jeffreydeanmorgan , he knew that the way to my heart was winning over my roommate and BFF @nikolainiceguy," she revealed.

"Jeff would send me letters with a PS added on for Nick, and that grew into shared Thanksgivings and Christmases and trips to Disneyland. And so 14 years later, I’m happy I got to celebrate both my guys today."

She continued, "Jeff, thank you for loving me by loving all the people who were important to me."

Augustus joined his parents at the The Cinema Society's screening of Mary Poppins Returns in 2018.

Three years later, 11-year-old Gus would guest star on his dad's hit AMC show as a walker. "We are super proud of Gusy Dean," the proud papa wrote on Instagram. "Thanks to @amcthewalkingdead and @gnicotero for making a dream come true… a damn hoot! Xxjd"

The parents had a scream taking their kids (with a pal) trick or treating for Halloween in 2018.

While spending Burton's 39th birthday in different places, Morgan took the time to reflect on what he loved so much about his wife.

"She… in a word? Perfect. The hottest. The smartest. Most thoughtful. Pretty damn funny. Easily the meanest according to our kids. Also hands down, the best mom… according to our kids…and me. Talented as hell," he wrote in part, before lamenting the fact that they were apart.

"[She's] ALWAYS, my best friend. And it’s her birthday. And I’m not with her. I should be. I should never miss her birthday. Ever. So… after this year, I won’t," he wrote.

He concluded the heartfelt message with, "I love you mrs morgan. I’m wishing you the happiest of days…. When I get home. Happy birthday. I’m real glad you were born… and SO recently too! xoxohusband."

The happy couple were spotted on the field at Kauffman Stadium during the 2016 Big Slick Celebrity Weekend on in Kansas City, Missouri. 

The family enjoyed a sunny summer day at the park — snow cones and all.

The couple was dressed to the nines in all black while attending Sophia Bush's wedding to Grant Hughes last year.

"I love this woman immeasurably," Morgan wrote, to which Burton replied: "You flirtin' with me??"

"Jeffrey is the same guy now that he was when I met him," the actress told PEOPLE while promoting her memoir, The Rural Dairies in 2020.

"He knew 100 percent who he was and that was a delight. Because I could be the one who could experiment. Being with someone so solid allowed me to grow."

It was a family affair for the Morgan clan as the entire crew worked together on the film Bloody Axe Wound. The experience, Morgan revealed in the caption accompanying the photo, "sealed" Gus' desire to "work in film."

Little George was in on the fun too, as she was pictured taking (or giving) some notes to her dad.

Burton snapped this sweet selfie with her hubby as they snuck onto the dance floor at Gus' homecoming — which she helped organize — last October.

Burton shared this adorable flick of Morgan smothering their firstborn in kisses. "As summer winds down, just a declaration of gratitude that the four of us got to be together. Watching @jeffreydeanmorgan with these kids is my happiest happiest happiest place," she wrote.

In the same post, the actress also shared this endearing pic of Morgan getting some cuddles with George.

Burton revealed that back to school shopping looks a little different in the Burton-Morgan household in this post from September.

"I suppose some families go back to school shopping at the mall or Target.
We opted for the @spirithalloween store and the @newyorkrenaissancefaire this weekend," she wrote.

"Why buy new sneakers when you can get leather armor and dragons?!?! And jousting is pretty much football…..with a stick and horses. Stay weird, everybody. ✨💖"
