The year 2025 has already become one of the most surprising years in Korean entertainment — not for scandals, but for weddings. From sudden announcements to long-kept secrets, more than a dozen stars have shocked fans by tying the knot.
KoreaBoo recently conducted a poll asking fans which celebrity “marriage reveal” caused the biggest stir in showbiz. Here are the top five celebrity weddings that sent fans into disbelief this year.
5. Minah (Girl’s Day) and Actor On Joo-wan
In July, fans were stunned when both Haewadal Entertainment and SM C&C confirmed that Minah and On Joo-wan were set to marry in November 2025. The announcement was shocking as the couple had never publicly confirmed their relationship before.
The two first met in the 2016 drama Beautiful Gong Shim and reconnected in the 2021 musical The Days. Their romance reportedly deepened over the years, with On Joo-wan standing by Minah during her father’s passing in 2024.
4. Ailee and Choi Si-hoon
When Ailee confirmed her relationship with Single’s Inferno star Choi Si-hoon in 2024, fans were already intrigued. But what really turned heads was their lavish April 2025 wedding at a luxury hotel in Gangnam.
The event gathered a guest list comparable to an award show, featuring celebrities like Yoo Jae-suk, Siwon (Super Junior), Baek Ji-young, Haha, Huh Gak, and members of g.o.d. Despite their three-year age gap, the couple was hailed as a perfect match.
3. Supermodel Irene Kim
On January 30, during Lunar New Year, Irene Kim announced her marriage at the age of 38. She kept her husband’s identity private, but reports revealed he is a businessman.
The wedding, held on May 23, was private and strictly closed to the media. Irene Kim shared that she felt “lucky and grateful” to have found a life partner who was truly in sync with her.
2. Kim Seul-gi and Yoon Doo-joon (Highlight)
In one of the biggest “fake-outs” of the year, tvN shocked the nation in August by posting a wedding invitation for actress Kim Seul-gi and idol-actor Yoon Doo-joon. The invite read as if the two were really tying the knot on August 17, sending fans into a frenzy.
The truth? It was all a publicity stunt for their The Catstody War, where the two play a married couple. Still, the realistic invite fooled fans and media alike, making it one of the most unforgettable moments of 2025.
1. Kim Jong-kook
Taking a massive 61% of the votes, Kim Jong-kook’s marriage announcement topped the list as the most shocking wedding of the year. After over 30 years in the industry and countless jokes about his bachelor status on variety shows, the 48-year-old “Sparta” star finally revealed he was getting married.
His bride, an 11-years-younger Korean-American CEO of a cosmetics company, was revealed to be based in Los Angeles. The couple had reportedly been dating since 2020.
To prepare for his new life, Kim Jong-kook purchased a luxury villa in Seoul’s Nonhyeon district, worth 6.2 billion KRW, which will serve as their marital home. His private wedding took place on September 5, 2025, with only family and close friends present.
With these whirlwind announcements, 2025 has proven to be a landmark year for celebrity marriages in Korea. But no twist has shocked fans more than the “forever bachelor” Kim Jong-kook finally settling down.
