Go Woori Announces Pregnancy Live on Radio Star: "Two Lines — Then They Called"

In one of the most unexpectedly joyful moments of the year on Korean television, former Rainbow member Go Woori used her April 1 appearance on MBC variety show Radio Star to announce something that no one in the studio — or at home — saw coming: she is seven weeks pregnant.

Sitting alongside fellow guests Jo Gap-gyeong, Chae Yeon, and Lee Chae-young of fromis_9, Go Woori kept her news close until the right moment, then delivered it with the kind of warm humor that has endeared her to fans for over a decade. The studio erupted.

"The Two Lines Appeared — and Radio Star Called the Next Day"

The timing of Go Woori's revelation was almost too perfect. She had just confirmed her pregnancy via a home test when, the very next day, she received a casting call from the Radio Star production team. For many, that kind of coincidence might inspire hesitation — but Go Woori decided it was a sign.

"Two lines appeared on the test, and the next day Radio Star called," she told the hosts, laughing. "I went back and forth on whether to say anything, but in the end I just thought — this feels right."

The pregnancy is the result of successful IVF treatment, a journey Go Woori has been on with her husband, a non-celebrity businessman she married in October 2022. The couple had been quietly trying to conceive for years. "My goal this year was to get pregnant," she admitted on air. "I kept failing. But this time, it worked."

Host Kim Gura captured the room's energy perfectly: "Your New Year's resolution came true — and you're telling us about it on April Fool's Day of all days." The irony was not lost on anyone. The baby's prenatal nickname, Go Woori shared, is Bokdungi — a Korean term of endearment meaning "little bundle of luck."

A Journey Five Years in the Making

Go Woori — born Go Na-eun on July 6, 1989 — debuted with Rainbow in 2009 under DSP Media, one of K-pop's most beloved second-generation girl groups. The seven-member group was known for hits like A, To Me, and Sunshine, building a dedicated fanbase throughout their seven-year run until disbanding in 2016.

While many former Rainbow members have pursued individual careers in acting, music, and variety, Go Woori found a second chapter with her Rainbow groupmate Cho Hyunyoung in the duo unit Rainbow18. The pair has maintained a consistent presence in the entertainment scene through events, performances, and variety appearances — proving that the bond between Rainbow members only grew stronger after the group's official end.

Her marriage in 2022 was followed by a period of relative privacy around her personal life. But Go Woori, never one to hide her genuine emotions, chose Radio Star — a show famous for drawing out celebrities' most candid stories — as the right venue to share this chapter.

"I honestly didn't plan to say it," she reflected on the show. "But I got there and thought — why not? This is happy news. I want people to celebrate it with me."

Even Pregnancy Won't Stop Her From Waterbomb

If there was any doubt that Go Woori's personality remains fully intact, this moment erased it. When conversation turned to her upcoming schedule — including a planned appearance at Waterbomb, the wildly popular outdoor water festival — she made clear she has no intention of canceling.

"I'm going to do music shows. I'm going to do Waterbomb. I'm doing it all," she announced with a laugh, to the delight of the audience. Host Kim Gura raised an eyebrow. Co-host Jang Doyeon looked equally amused.

It was a quintessentially Go Woori moment — earnest, funny, and completely unfiltered. The clip quickly circulated online, with fans flooding social media with a mix of congratulations and affectionate disbelief at her energy levels.

She also revealed that six fortune-tellers had independently predicted that 2026 would be a year of both great success and pregnancy for her. "They all said it. I thought it was just something fortune-tellers say," she laughed. "Turns out they were right."

Rainbow18: Still Shining

Go Woori's appearance on Radio Star also shed light on the current state of Rainbow18. She and Cho Hyunyoung have been active in the performance circuit, drawing enthusiastic crowds at events across Korea.

"People are always so happy when we show up to an event," she said. "It genuinely relieves stress. There's something special about performing for people who have been fans since the original Rainbow days."

Rainbow18 operates in a particular lane of K-entertainment — veteran idol units who carry nostalgia, stage presence, and genuine camaraderie that newer acts are still building toward. For fans of second-generation K-pop, groups like Rainbow18 represent something irreplaceable: the feeling of watching artists who have been through everything together still choosing to perform together.

This year, it seems, will add a new dimension to that story. Go Woori becoming a mother while continuing to perform is not just personal news — it is a statement about what the next chapter of Korean idol culture can look like.

Fan Reaction: Pure Joy

The response from fans online was immediate and overwhelming. The hashtag for Go Woori trended on Korean social media platforms within hours of the broadcast, with supporters flooding the comments with heart emojis, blessing messages, and screenshots of her infectious smile from the episode.

Many longtime Rainbow fans noted the full-circle quality of the moment — a member who brought so much happiness to others over the years now sharing the happiest news of her own life. "Woori unnie deserves every bit of this," read one widely shared comment. Others highlighted the IVF aspect of the announcement, calling her openness about the process brave and important.

In Korea, public figures discussing fertility treatments and IVF openly remains relatively rare, making Go Woori's candid disclosure all the more meaningful to fans who have experienced similar journeys or know someone who has.

For Go Woori, the April 1 broadcast was many things at once: a variety show appearance, a pregnancy announcement, a reunion with a generation of loyal fans, and an unmistakable signal that her next era is just beginning. Bokdungi, wherever you are — your mother is already making the whole country smile.
