Sophia Bush shares photos from 'perfect' birthday celebrations

Sophia Bush is reflecting on what she says was a "perfect" birthday.

The "One Tree Hill" alum shared photos from her 42nd birthday on Instagram Tuesday evening, showing highlights from her big day including a selfie with partner Ashlyn Harris, a picture with balloons and a short video from a bowling alley.

"'That’s gonna be a strike*' *it was not, but it was close. And my birthday was perfect," Bush wrote in the caption of her post.

Harris, a former U.S. women's soccer player, also posted a tribute to Bush for her birthday.

"Happy birthday beautiful. I hope today feels special and full knowing how much we love you," she wrote in the caption of an Instagram post. "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. Happy born day baby."

Bush responded to Harris in the post's comment section, writing, "Last year I got free. This year I found the very best love in the very most unexpected place. I may never get over the gift of it. Thank you for putting me back together. For making my second birthday even better than my first. And for reminding me what the sound of my unbridled laughter sounds like. You are magic. You are my best present."

Bush first opened up about her relationship with Harris in an essay for Glamour back in April, in which she detailed the beginning of their relationship and her experience with the LGBTQIA+ community.

"Falling in love with her has sutured some of my own childhood wounds, and made me so much closer to my own mother," she wrote at the time.

Bush was previously married to her "One Tree Hill" co-star Chad Michael Murray from 2005 to 2006 and to Grant Hughes from 2022 to 2023.
