The Timeline of the Private Relationship and Public Breakup

The relationship between Post Malone and Jamie Park was characterized by extreme discretion, a stark contrast to the rapper's previous high-profile, albeit still private, romance with Ashlen Diaz. This timeline highlights the key milestones that were eventually revealed to the public.

A Quiet Beginning (2020)

Post Malone and Jamie Park were first linked publicly around October 2020, though they had likely been dating for some time prior. Unlike many celebrity couples, their first public appearances were low-key, often just being spotted by fans at airports or during quiet outings. The lack of red-carpet appearances or social media posts allowed their relationship to flourish away from media scrutiny.

Engagement and Fatherhood (2021–2022)

The couple took a major step in 2021 when they reportedly became engaged. This news, like most of their life, was never officially confirmed by the rapper but was later referenced in court documents. The biggest milestone came in May 2022, when Post Malone casually announced on *The Howard Stern Show* that he was expecting his first child. Shortly after, in June 2022, he confirmed the birth of his daughter and also revealed that he was engaged to the baby's mother, cementing Jamie Park's status as his fiancée.

Post Malone often spoke about how fatherhood and his fiancée had changed his life, mentioning them as the inspiration for a newfound sobriety and a desire to be more grounded. He purchased a large, secluded home in Utah to raise his family away from the chaos of Hollywood, emphasizing his commitment to a private family life.

The End of the Engagement and Custody Battle (Late 2024–2025)

The engagement quietly ended in late 2024 or early 2025. The breakup was initially suspected when Post Malone was seen with a new partner, Christy Lee, around the beginning of 2025. The definitive confirmation, however, came in April 2025 when Hee Sung "Jamie" Park filed court documents in Los Angeles Superior Court requesting primary physical custody of their 3-year-old daughter.

It was these official legal filings that finally revealed her full name, Hee Sung Park, to the public. Jamie Park reportedly sought to relocate the child from Utah, which complicated the custody arrangement and led to the protracted court battle. The legal proceedings focused on visitation rights, child support, and the final custody agreement, making headlines in the spring of 2025.

The Final Custody Settlement and Current Status

The most recent and definitive news regarding Post Malone and his ex-fiancée is the finalization of their custody agreement in late 2025. According to reports, the former couple reached a private and sealed agreement on all pertinent issues, including custody, visitation, and child support for their daughter.

The settlement means that the highly private details of their co-parenting plan will not be made public, which aligns perfectly with the couple's long-standing commitment to protecting their daughter's privacy. The withdrawal of Jamie Park's petition for custody relocation suggests that the final agreement was a compromise that satisfied both parties, allowing them to move forward in a stable co-parenting environment.

The Topical Authority: Why Jamie Park’s Identity Was Kept Secret

The extreme measures taken by Post Malone to shield Jamie Park and their child from the public eye is a major point of fascination and topical authority surrounding their relationship. In a 2022 interview, the singer explicitly stated his desire to keep his family life private, citing the intense scrutiny and potential danger that comes with his level of fame. He has consistently expressed that he wants his daughter to be able to make her own decisions about her public life when she is older, a sentiment that led him to keep his fiancée's identity a secret for so long.

This dedication to privacy is also why the public knows virtually nothing about Jamie Park's career or personal background. She is not an actress, model, or socialite; she is simply the mother of his child, and her lack of a public profile allowed the couple a degree of normalcy that is rare for a superstar of Post Malone’s caliber. The only reason her name is now known is due to the mandatory public records associated with a court filing in the custody proceedings. This makes the revelation of Hee Sung "Jamie" Park a truly unique and fresh piece of celebrity news, not just a rehashing of old rumors.

Entity Expansion: The Other Key Relationships

While Hee Sung "Jamie" Park is the official "ex-fiancée," Post Malone has had other significant relationships that are often confused with her, adding to the topical complexity:

• Ashlen Diaz: Post Malone’s ex-girlfriend from 2015 to 2018. She was with him as his career exploded following the release of his hit song "White Iverson." Their breakup was reportedly due to his demanding tour schedule, and the relationship was later linked to a lawsuit concerning a $350,000 breakup settlement and allegations of abuse, which Post Malone’s team denied.
• Christy Lee: Post Malone’s current girlfriend, whom he began dating around the time of his separation from Jamie Park in early 2025. Their relationship became public after they were spotted together following the breakup of his engagement.

In conclusion, the story of Post Malone's ex-fiancée, Hee Sung "Jamie" Park, is less about scandal and more about the intense efforts of a celebrity to maintain a private life. The recent, officially settled custody battle in late 2025 has provided the final, concrete details on the woman who was his partner during his rise to global superstardom, confirming her identity and the quiet conclusion of their engagement.
