The 36-year-old singer took to Instagram on Sunday to share snaps from her time at BMI's Songwriters Festival, which was held in Maui, Hawaii, over the weekend.
In between performances and songwriting sessions with the likes of Maren Morris, Willie Nelson and Randy Houser, Lambert and her husband took some time for themselves.
In one shot, the grinning pair pose during sunset at their hotel, Fairmont Kea Lani, with palm trees in the background. Another pic features the couple smiling in a selfie, which they snapped in front of a waterfall.
"Thank you @bmi songwriters festival for having us back this year," Lambert captioned the photos. "Maui is a magical place. Playing music here with great friends is a dream. Headed home for family time!"
The "All Comes Out in the Wash" singer also shared some moments from her trip to Hawaii on her Instagram Story.
"It's really good to be genuinely happy,” she said of married life. “You almost don't realize that you're not until you get there and you're like, 'Man, I didn't know that there was a level of comfort and happiness out there that existed like that.'"
"He's a really positive, upbeat person, so that's good for me because I tend to lean negative -- we Scorpios do -- so we're a good balance," she added. "He keeps me in check. He's just normal and cool and always smiling. [When] someone’s that happy, there's no choice but to [be happy too] and it's really great."
