Who Is Dr. Lilly Jay? 5 Things to Know After Her Ethan Slater’ Divorce Essay
Before Ethan Slater began dating Ariana Grande, he spent more than four years married to his high school sweetheart, Dr. Lilly Jay.
Slater and Jay tied the knot in 2018 and share a son, born in fall 2022. Less than a year later, they split up, and Slater’s relationship with Grande became public knowledge.
Jay opened up about their public split in an essay for The Cut, published on Thursday, December 19, titled How Does My Divorce Make You Feel? The title is a reference to her work as a clinical psychologist.
“No one gets married thinking they’ll get divorced,” she wrote, “But I really never thought I would get divorced. Especially not just after giving birth to my first child, and especially not in the shadow of my husband’s new relationship with a celebrity.”
