Halsey and Alev Aydin have broken up.

"It's an amicable split," a source told PEOPLE. "They're planning to co-parent."

The "Without Me" singer was first linked to the Turkish-American screenwriter in 2018 when he was tapped to write the screenplay for a biopic about and starring Halsey. However, the pair began a romantic relationship that curtailed the project.

In response to a tweet asking why the film never happened, the star replied, "bc alev was supposed to be writing it the past 3 years and we slowly fell in love instead. you know the rest!"

Halsey, who has been open about their struggles with endometriosis and infertility, shared that they were expecting a baby with Aydin in 2021 after a previous miscarriage. "For a long time, I didn't think that having a family was something I was going to be able to do, and it's very, very important to me," the singer wrote in the Manic album notes.

The couple welcomed their son, Ender, in July 2021. According to court documents obtained by PEOPLE, Halsey is seeking full physical custody of the child following their split from Aydin.

From biopics and babies to their breakup, here is a complete timeline of Halsey and Alev Aydin's relationship.
