Post Malone, born Austin Post, is engaged to his on-again, off-again girlfriend, Christy Lee. The couple, first linked in March 2025, announced their engagement on August 19, 2026.

Lee, who works as a fashion stylist and creative director, has a background in strategic design and management from Parsons School of Design. Her professional experience includes personal styling, editorial direction, and assisting with red carpet events and brand campaigns for clients such as Bella Thorne and Brooks Nader. She documents her work and travels on her Instagram account, which boasts nearly 30,000 followers.

The pair were first photographed together in Rome in March 2025. Subsequent sightings in Paris that April showed them holding hands and sharing public displays of affection. However, reports emerged just two months later that the couple had separated. It is unclear when they reconciled.

Prior to his relationship with Lee, Post Malone had ended his engagement to Jamie Park toward the end of 2024. The couple share a daughter born in May 2022.

News of the engagement broke when a fan page shared photos of the couple, with Lee displaying a large engagement ring and wearing a "Bride to be" sash. A friend also shared a video of a surprise engagement celebration in Utah, where the couple was seen kissing and posing for photos. Mascagni Hotel in Rome served as the setting for the couple's first public appearance as a pair in March 2025.
