It’s unclear when Halsey and the screenwriter started dating, but they were spotted out in LA together in October 2020. They later revealed to Allure that the pair had known each other for years before they got together romantically. “Alev and I have been really good friends for four years,” Halsey told the publication in July 2021. “And when the stars aligned, our relationship became romantic, and it was pretty evident that he and I were both like, ‘Oh, my gosh! You’re the person I’m supposed to start a family with.’ A lot of people had opinions about that.”
In January 2021, Halsey announced they were pregnant, which Aydin shared on his Instagram Story. Aydin also commented on the post, writing, “Heart so full, I love you, sweetness,” to which Halsey replied, “I love you!!!!! And I love this mini human already!”
Halsey gave birth to her and Aydin’s first child together, Ender Ridley Aydin, on July 14, 2021, announcing the news five days later on Instagram with a black-and-white photo of the pair cradling Ender in the hospital. “Gratitude. For the most ‘rare’ and euphoric birth. Powered by love,” they captioned the post.
On April 25, 2023, it was reported that Halsey and Aydin split up after three years of dating, a source confirmed to POPSUGAR. The source shared that the breakup was amicable. The singer requested full physical custody of their son, Ender, and requested visitation for Aydin, according to Los Angeles County court documents obtained by POPSUGAR. The insider clarified that the custody arrangement was due to the singer’s summer tour.
