The Shocking Split: Who Is Post Malone's Ex-Fiancée, Hee Sung "Jamie" Park, And The Truth About Their Custody Battle?

Contents

The private world of Austin Richard Post, known globally as Post Malone, was dramatically thrust into the spotlight in 2025 following the end of his long-term engagement and a subsequent, highly publicized legal battle. For years, his partner was known simply as "Jamie," a deliberate choice by the couple to shield her and their family life from the intense glare of celebrity. Now, as of late December 2025, the full story of his former fiancée, the mother of his child, and the dramatic custody dispute that followed their split has finally emerged, revealing the identity of Hee Sung "Jamie" Park and the complex co-parenting arrangement they have settled on.

The separation, which became public knowledge in early 2025, ended one of the most secretive relationships in the music industry. While Post Malone has moved on, now publicly dating Christy Lee, the focus remains on Hee Sung Park and the quiet strength she displayed during the recent seven-month-long legal proceedings concerning their young daughter. This deep dive uncovers everything known about the woman who was once set to marry the "Circles" rapper and the fresh details surrounding their unexpected breakup and successful custody resolution.

Hee Sung "Jamie" Park: Biography and Profile

Hee Sung "Jamie" Park is a figure defined by her resolute commitment to privacy, making her one of the most mysterious partners in modern celebrity culture. Unlike many significant others of A-list stars, details about her life—career, education, and even her age—have been meticulously kept out of the public domain for years. Her identity was only officially confirmed through court filings in April 2025, following the initiation of her custody case.

  • Full Name: Hee Sung Park
  • Nickname: Jamie
  • Ethnicity: Korean-American (implied by name and reports)
  • Relationship Status (2025): Ex-Fiancée of Post Malone (Austin Richard Post)
  • Engagement Timeline: Reportedly engaged in 2021, though never officially announced.
  • Relationship Duration: They were together for several years before their split in early 2025.
  • Children: One daughter, born in May 2022.
  • Career/Profession: Unknown. She maintains an extremely low profile, with no public social media presence or known professional affiliations, reinforcing her desire for anonymity.

The couple’s relationship was a quiet sanctuary away from the chaos of Post Malone’s global superstardom. They reportedly met through mutual friends, and their connection blossomed far from the Hollywood scene, with the rapper often referring to her simply as "my fiancée" in interviews, steadfastly refusing to share her name or any personal details. This deep level of secrecy was a hallmark of their bond until the unfortunate circumstances of their split forced her name into legal documents.

The Shocking Split and New Relationships in Early 2025

The end of Post Malone and Hee Sung Park's engagement came as a surprise to many fans who had celebrated the birth of their daughter in May 2022. The couple's separation occurred quietly around early 2025, with news of the breakup only surfacing publicly in March 2025. This timeline coincided directly with the first public sightings of Post Malone with a new romantic partner, signaling a decisive end to his life with Jamie.

The "Sunflower" singer quickly moved on, and by March 2025, he was publicly linked to a woman named Christy Lee (sometimes also referred to as Kristi Lee). The two were spotted together frequently, engaging in public displays of affection, including a high-profile shopping spree and kiss in Paris. Christy Lee's identity is slightly less guarded than Jamie's; reports suggest she is a Parsons School of Design student and an aspiring stylist. This new, more public relationship stood in stark contrast to the intensely private years Post Malone spent with Hee Sung Park.

The swift transition to a new partner fueled significant media speculation, but the rapper and his ex-fiancée remained silent on the reasons for their separation. The focus quickly shifted from the breakup itself to the welfare of their daughter.

The Intense Custody Battle and Final Settlement

The true drama of the Post Malone and Hee Sung Park separation unfolded in the legal arena. While the couple initially maintained a private, amicable 50/50 co-parenting agreement, this arrangement was challenged in April 2025 when Hee Sung Park filed documents in Los Angeles Superior Court requesting primary physical custody of their three-year-old daughter.

This filing brought the previously unknown details of their family life into the public eye, including Hee Sung Park's full name. The request for primary custody suggested a breakdown in their co-parenting relationship, sparking a seven-month-long legal dispute. The core of the matter centered on establishing a formal schedule for custody, visitation, and financial support for the child.

Key Developments in the 2025 Custody Case:

  • Initial Filing (April 2025): Hee Sung Park filed for primary physical custody, requesting that she and Austin Richard Post share joint legal custody.
  • Protracted Dispute: The battle lasted approximately seven months, a significant period for a high-profile case, indicating complex negotiations.
  • Resolution (Late 2025): In a major update, reports confirmed in late 2025 that Post Malone and Hee Sung Park had officially reached a settlement.

The settlement agreement was reached out of court, allowing the former couple to avoid a full trial and keep the specific details of their co-parenting plan confidential. This resolution ensures that both parents have a structured agreement for raising their daughter, covering custody, visitation, and child support, marking a return to a more stable, albeit co-parenting, relationship for the benefit of their child. The successful settlement allows Post Malone to focus on his career and new relationship with Christy Lee, while Hee Sung Park can continue to maintain the private life she has always valued.

Post Malone's Journey to Fatherhood and Co-Parenting

Post Malone has often spoken with genuine emotion about his daughter, whose name remains private. He has consistently described fatherhood as the most important thing in his life, a change that has profoundly influenced his music, lifestyle, and overall demeanor. He famously cleaned up his act, reducing his drinking and focusing on better health after her birth, citing his daughter as the main motivation.

His co-parenting journey with Hee Sung Park, though rocky in 2025 due to the custody filing, appears to have stabilized with the final settlement. The rapper has embraced the role of a devoted father, often sharing how his daughter has brought immense joy and perspective to his life. The entities involved—Austin Richard Post, Hee Sung Park, and their daughter—now navigate a new normal of celebrity co-parenting, a challenging dynamic that requires mutual respect and a shared commitment to the child's well-being.

Ultimately, while Hee Sung "Jamie" Park may no longer be Post Malone's fiancée, she remains a central figure in his life as the mother of his child. Her identity, once a secret, is now known, but her fierce dedication to privacy ensures that she will likely continue to live a life away from the public eye, focusing on her role as a mother and the successful co-parenting of their daughter.
