It’s rare for an actor to go from fashion modeling to winning an Emmy in the same lifetime, but Lee Jung-jae has done exactly that – born in Seoul in the early 1970s, he spent decades building a film career before Squid Game turned him into a household name overnight. This profile sorts verified facts from the rumors about his personal life, relationships, and net worth.

Full Name: Lee Jung-jae · Born: December 15, 1972 (Seoul, South Korea) · Occupation: Actor, filmmaker, businessman · Famous For: Squid Game (2021) · Instagram: @from_jjlee · Net Worth: Estimated $5–10 million

Seven key data points, one pattern: nearly all reliable sources agree on the basics of his career, but personal details remain disputed.

Who is Lee Jung-jae and why is he famous?

Early life and education

Lee Jung-jae was born on December 15, 1972, in Seoul, South Korea (Encyclopaedia Britannica). He studied drama at Dongguk University (Wikipedia (community encyclopedia)), though his first public exposure came through fashion modeling. He reportedly made his acting debut in the 1993 television series Dinosaur Teacher (YouTube (video biography)).

Career beginnings

His breakout film role is often identified as the 1998 movie An Affair (IMDb (film database)). Over the next two decades, he built a solid filmography in South Korean cinema, working with directors like Park Chan-wook and appearing in hits such as Deliver Us From Evil (IMDb (film database)).

Rise to fame with Squid Game

Squid Game premiered on Netflix in 2021 and became the project that boosted Lee Jung-jae to global renown (Encyclopaedia Britannica). He played Seong Gi-hun, a debt-ridden gambler who survives a deadly children’s game. The role earned him the Primetime Emmy Award for Outstanding Lead Actor in a Drama Series in 2022 (Wikipedia (community encyclopedia)). That win is widely described as the first for a non-English-language performance and the first by an Asian man in that category.

Bottom line: Lee Jung-jae transitioned from model to respected actor over three decades, but Squid Game catapulted him into an unprecedented level of international recognition.

Does Lee Jung-jae have a child?

Public knowledge about children

There is no public confirmation that Lee Jung-jae has a child. Reliable sources such as Encyclopaedia Britannica make no mention of children, and no reputable entertainment outlet has reported any. The absence of evidence suggests he does not have children.

Relationship status

Lee Jung-jae has never been married (Wikipedia (community encyclopedia)). He has been in a long-term relationship with businesswoman Lim Se-ryung, an heiress to Daesang Group (Encyclopaedia Britannica). The couple keeps their private life very quiet.

Bottom line: No verified information exists about Lee having a child. His only confirmed long-term relationship is with Lim Se-ryung, not with any of his on-screen partners.

Is Lee Jung-jae in a relationship?

Current relationship rumors

As of 2025, entertainment coverage frequently reports Lee Jung-jae and actress Lim Ji-yeon as co-stars in a romantic comedy, not as a dating couple (Soompi (K-pop/K-drama news)). They starred together in the 2025 drama Nice to Not Meet You, but no credible source confirms a real-world romance.

Past relationships

Britannica notes that Lee has been in a “long-term relationship” with businesswoman Lim Se-ryung (Encyclopaedia Britannica). No other past relationships have been publicly documented.

Bottom line: The persistent social media pairing of Lee and Lim Ji-yeon stems from their on-screen chemistry, not from real-life dating. His known partner remains Lim Se-ryung.

What is the age gap between Lee Jung-jae and Lim Ji Yeon?

Age difference details

Lee Jung-jae was born in 1972; Lim Ji-yeon was born in 1990. The difference is 17 years (The Straits Times (Singapore news outlet)). When the drama Nice to Not Meet You aired, viewers focused heavily on that gap, with some calling it controversial.

Public reaction

The Straits Times reported that the age gap became “sparks controversy” among K-drama fans. However, both actors have dismissed the issue, with Lim Ji-yeon stating that she “didn’t think about the age difference while acting” (The Straits Times (Singapore news outlet)).

Bottom line: The 17-year age gap between Lee (52 in 2024) and Lim (35) is real but largely irrelevant to their professional relationship. Media attention on the gap distracts from their work.

Why is Lee Jung-jae not married?

Personal choices

Lee Jung-jae has never been married and has made no public statements explaining why (Wikipedia (community encyclopedia)). He is known to be intensely private about his personal life.

Career focus

With a career spanning three decades and a recent global breakthrough, it’s plausible that Lee prioritized his acting and business ventures over marriage. He has built a diversified portfolio including a restaurant chain and film production (IMDb (film database)).

Bottom line: Without an official statement, any reason for his unmarried status is speculation. His long-term relationship with Lim Se-ryung suggests he values privacy over public commitment.

“I never imagined I would be here. This is for all the Korean actors who have been overlooked.”

“I didn’t think about the age difference while acting. The story is what matters.”
