Who is IU's Boyfriend? The Kpop Star's Relationship Details

In the fast-paced and often ephemeral world of South Korean entertainment, few stories have captured the public imagination quite like the relationship between global superstar IU (Lee Ji-eun) and A-list actor Lee Jong-suk.

As of April 2026, the couple remains the undisputed “gold standard” for celebrity pairings, having successfully navigated over three years of public dating while maintaining two of the most demanding careers in Asian media.

Their journey from “awkward colleagues” to “soulmates” is a narrative that fans- collectively known as UAENA and WithJS- continue to follow with a mixture of reverence and excitement.

The confirmation of their relationship on December 31, 2022, was a historic moment for the industry.

Unlike many idol relationships that face intense scrutiny or backlash, the union of IU and Lee Jong-suk was met with overwhelming warmth. This was largely due to their long history.

The two first met in 2012 as co-hosts for the SBS music program Inkigayo. At the time, Lee Jong-suk famously admitted that he found IU’s enthusiasm for dressing up in elaborate costumes- such as Peter Pan or Leon- slightly “annoying” because of his shy nature.

However, he later clarified that she was the one who kept him grounded during his early days of fame.

Reflecting on those early years, he once noted in a letter to fans,

“She was someone who was always there in a corner of my heart, a bit of a strange person who stayed with me.”

A Relationship Built on Mutual Professional Respect

One of the defining characteristics of their relationship in 2026 is how they balance their massive individual “brands” while supporting one another’s artistic growth.

IU, often referred to as the “National Singer,” has spent the last year expanding her influence through her recent work in the 2026 drama Perfect Crown (also known by the title 21st Century Grand Lady).

During the press circuit for the show in April 2026, she spoke candidly about the creative synergy she shares with her partner.

“Because we are in the same profession, we naturally talk about acting a lot,” she shared during a roundtable interview on her ‘이지금’ (IU Official) YouTube channel.

“If there is a scene that I really don’t understand or a character beat that feels off, I make an SOS call to my boyfriend.

He has a way of looking at scripts that is very different from mine, and it helps me see the bigger picture.”

This “SOS call” dynamic has become a favorite anecdote among fans, highlighting a level of domesticity and professional reliance that is rare in high-profile celebrity couples.

Lee Jong-suk, for his part, has never been shy about his admiration for IU’s work ethic.

He has often been spotted wearing IU’s concert merchandise, such as “The Golden Hour” hoodies, or carrying “The Winning” accessories in his casual paparazzi shots.

When asked about his influence on her music, he jokingly told reporters,

“I’m just her number one listener. I don’t give musical advice; I just make sure she has enough snacks when she’s in the studio for twenty hours straight.”

Navigating the 2026 “Ratings War” and Future Outlook

The year 2026 has been particularly interesting for the couple due to their overlapping schedules.

With IU starring in Perfect Crown on MBC and Lee Jong-suk leading the massive Disney+ production The Remarried Empress, the media dubbed the period the “Battle of the Households.”

Despite being “rivals” for the weekend ratings, the couple’s personal bond remains unshaken.

In fact, just this week on April 22, 2026, Lee Jong-suk went viral for a “lovestagram” post where he shared photos of cherry blossoms.

Fans quickly noticed a character made of fallen petals that resembled “Tweety Bird”- the character IU famously uses for her profile pictures. He didn’t need a caption; the flower-shaped emoji said it all.

Beyond the cameras, the couple is frequently praised for their maturity. In an industry where “dating rumors” can derail a career, IU and Lee Jong-suk have managed to normalize their relationship.

IU once addressed her philosophy on love during a recent broadcast with her co-stars:

“If you truly love someone, you don’t constantly talk about love. Love is something that resides deep in your heart without needing to be overtly displayed.”

Since 2022, they have quietly continued their relationship and are now considered a “fourth-year couple.”

As we move through April 2026, speculation regarding their future- including rumors of private wedding preparations- continues to circulate in the tabloids.

However, both stars remain focused on the present.

Whether they are collaborating on philanthropic efforts or simply supporting each other’s global tours, they represent a new era of Hallyu stardom where personal happiness is celebrated alongside commercial success.

As Lee Jong-suk once beautifully put it:

“She makes me want to become an even better person, and that is the greatest gift anyone can give.”

As the record-breaking numbers for their respective shows suggest, the world is more than happy to support them.
