Thomas Rhett and wife Lauren Akins' little gal-entines, Willa Gray and Ada James, will melt your heart.

Akins turned to Instagram on Cupid's holiday, Valentine's Day, to share a series of photos of the couple's two young daughters — Willa in a pink dress and Ada in an adorable animal sweatshirt, both sporting festive red headbands with two hearts on top.

In the photo collage (flip to see them all) Willa Gray holds her little sister's hand as they pose for a stationery picture and stroll along the sidewalk before sharing a sweet hug. Alongside the photos, Akins gushed about what a loving older sister Willa is and how much the two appreciate one another.

"Sweet sister love on this Valentine’s Day," she writes alongside several heart and crying emojis. "Watching Willa Gray be the sweetest big sister melts my heart! She loves Ada James so well and AJ isn’t having a good day until she’s with her 'Seeser.'"

The family welcomed both daughters in 2017 — Willa by adoption and Ada biologically that summer.

The Rhett (Akins) family recently paid an exciting visit to Sesame Street when the country star was asked to sing a new song celebrating the iconic children's television show, "This Is My Street." The couple of course shared photos of their crew meeting Big Bird, Elmo, Bert and Ernie and many of the other famous puppets.

Rhett recently scored his twelfth No. 1 hit with "Sixteen," the fifth single off his highly successful album Life ChangesHe'll embark on the Very Hot Summer Tour with his father, multi-chart-topping songwriter Rhett Akins, and fellow hitmakers Dustin Lynch and Russell Dickerson joining as opening acts.
