The Huening Siblings Take the Spotlight

The spotlight shone brightly on a remarkable family connection as the Huening siblings captivated attendees at Seoul Fashion Week 2025.

Are Hueningkai and Bahiyyih siblings?

Despite their individual careers in different K-pop groups, HUENINGKAI and HUENING BAHIYYIH are indeed biological siblings with an extraordinary family legacy. Born to a European father and Korean mother, HUENINGKAI (born August 14, 2002) performs with TXT, while his younger sister BAHIYYIH (born July 27, 2004) shines in KEP1ER. Together with their elder sister Lea Navvab, a former VIVA member and current influencer, they form what many consider "the most popular sibling trio in the K-pop industry".

Their arrival at Dongdaemun Design Plaza

The brother-sister duo arrived together at the red carpet, specifically attending the Kwak Hyunjoo collection. Subsequently, they reunited with sister Lea for a memorable group photo that delighted fans. Their joint appearance was particularly special as they rarely share professional engagements, though they previously collaborated for a GQ Korea photoshoot.

Public and media reaction to their appearance

Social media exploded with admiration for the siblings. Fans commented, "They each have their own style. Love it!" and "A family full of models I swear!!!". Media outlets praised their "regal visuals and model-like proportions".
