Riley Keough is celebrating her sisters on their birthdays! To commemorate the occasion, Riley shared some rare throwback photos on her Instagram, celebrating twins Harper and Finley's 17th birthday.
The photos shared on Riley's story show her carrying her sisters when they were younger. One image shows Riley with one of her sisters over her shoulder, with the two smiling towards the camera. The second image shows Riley and one of the twins on the beach, with Riley carrying her in her arms.
"My angels are 17 today," she wrote.
Harper and Finley are Riley's half-sisters and the daughters of Lisa Marie Presley and Michael Lockwood. Riley is the daughter of Presley's previous partner, Danny Keough. Presley and Keough shared Riley and Benjamin, who passed away in 2020.
While Harper and Finley grew up relatively away from the spotlight, the girls now share posts on social media. This past January, they commemorated their mother on the anniversary of her death. Finley shared a throwback photo of her mother holding on to the twins when they were babies, writing, "2 years. I love you always."
Riley reposted the image, adding a heart emoji.
Harper shared another photo, showing her a little older, alongside her twin sister and mother. "I can't believe it's been 2 years, I miss you and love you so much mama," she wrote. Riley also reshared the image, adding another heart.
Riley's sweet relationship with her little sisters
Riley Keough is often private with her personal life, but has begun sharing more about her sisters in recent years. "Happy Sweet 16 to my angel girls," she wrote in an Instagram post last year. "You are the most special girls in the whole wide world. I am so lucky to be your big sissy."
Riley has also opened up about her relationship with her mother, even completing a memoir that Lisa Marie had begun to write before her death. The book, titled "From Here to the Great Unknown," came out last year, with Lisa Marie leaving behind tapes documenting her life that Riley explored as she was grieving the monumental loss.
“What she wanted to do in her memoir, and what I hope I’ve done in finishing it for her, is to go beneath the magazine headline idea of her and reveal the core of who she was," said Riley to PEOPLE. "To turn her into a three-dimensional human being: the best mother, a wild child, a fierce friend, an underrated artist, frank, funny, traumatized, joyous, grieving, everything that she was throughout her remarkable life. I want to give voice to my mother in a way that eluded her while she was alive.”
