Sophia Bush is ready to celebrate Ashlyn Harris.
The One Tree Hill alum—who confirmed her relationship with the soccer player in April—shared a sweet social media tribute in honor of Ashlyn’s Oct. 19 birthday.
“You are the sun, in human form,” Sophia wrote in a Oct. 20 Instagram post alongside a photo of the pair going in for a kiss. “You light up the world and warm each and every person you touch. There is no one like you, and everyone who knows you knows it’s true.”
And Sophia—who also reshared Ashlyn’s Instagram Story to her own, revealing the couple were spending the 39-year-old’s birthday on vacation—emphasized how lucky she feels to be Ashlyn’s partner.
“We are all so lucky,” she continued. “And I am the absolute luckiest. First of many together (You better live forever, woman, we have adventures to go on!) Happy Birthday baby. I love you with my whole soul.”
Of course, Sophia’s latest declaration of affection comes after Ashlyn—who shares kids Sloane, 3, and Ocean, 2, with ex Ali Krieger—shared an equally loving celebration for the 42-year-old’s birthday in July.
“I hope today feels special and full knowing how much we love you,” Ashlyn wrote to Instagram at the time. “You are such a gift in this world. To see you shine and happy fills us all up. I love your heart Soph—I love everything about you.”
Throughout their six months in the public eye, Sophia and Ashlyn have detailed their affections for each other. And the Chicago P.D. star previously explained why she feels like sharing how much she loves Ashlyn at every opportunity.
“Falling in love with her has sutured some of my own childhood wounds, and made me so much closer to my own mother,” Sophia previously wrote in a Glamour essay, where she detailed her relationship with Ashlyn. “Seeing Ashlyn choose to not simply survive, but thrive, for her babies has been the most beautiful thing I've ever witnessed a friend do. And now I get to love her. How lucky am I?”
