Heo Sol-ji

Heo Sol-ji, known mononymously as Solji, is a South Korean singer and vocal trainer. She is the leader and main vocalist of the K-pop girl group EXID, a role she has held since joining the group in July 2012. Her powerful vocals and technical skill have made her one of the most respected singers in the industry, a reputation built on years of experience as a trainer before her idol debut.

Beyond her group work, Solji has carved out a solo identity. In August 2025 she announced her first solo concert, "Our Memory," and as of 2026 she serves as a judge on the television competition "The King of Strings 3." Her Instagram following sits near 966,000, and her YouTube channel has accumulated over 46 million views, reflecting a dedicated fanbase that admires both her artistry and her warm, family-oriented personality.

Born in Seoul's Gwanak district, Heo Sol-ji grew up in the capital and attended Seongji Girls' High School. Her musical journey began in 2006 when she was scouted by Friday Entertainment and debuted as half of the ballad duo 2NB. The pair performed together for four years, releasing music in a genre far removed from the K-pop she would later embrace.

When 2NB disbanded in 2010, Solji did not leave music behind. She pivoted into vocal training, coaching aspiring singers with the technical knowledge she had gained on stage. That work proved pivotal. Through her training connections, she crossed paths with the members of EXID, a group that had debuted in 2012 but was still searching for its sound. Impressed by her voice and experience, the group invited her to join as leader and main vocalist in July 2012, a decision that would alter the course of her career. [edit]

Solji's arrival in EXID in July 2012 marked the beginning of a new chapter. As leader and main vocalist, she helped steer the group through its early years, and by 2015 the group had become a household name in K-pop. That same year she made her acting debut with a cameo in the television series The Producers.

Health issues forced a hiatus in 2017. In January 2018, at age 28, she underwent orbital decompression surgery, a procedure that removes part of the eye socket walls. The recovery kept her from group activities for months, but she returned triumphantly in November 2018 with EXID's single "I Love You," a comeback Billboard covered as the group's return "as a quintet after a hiatus from lead vocalist Heo Solji."

She continued to expand her range: in 2019 she appeared in the documentary EXID: Me & You, and in 2020 she took a role in the series The Spies Who Loved Me. In August 2025 she announced her first solo concert, "Our Memory," promoted with an ethereal poster that hinted at a dreamy, sentimental direction. As of 2026, she is a judge on "The King of Strings 3," a competition show where she has shown a cautious, thoughtful approach to controversy. [edit]

Solji is widely regarded as one of K-pop's most technically gifted vocalists, a reputation forged during her years as a vocal trainer. Her singing is marked by power, control, and emotional depth, qualities that have earned her respect from peers and fans alike.

Her public persona is warm and down-to-earth. She shares glimpses of her life on Instagram, where her handle "솔지 🩷 SOLJI" and her frequent heart emojis project a gentle, affectionate image. Fans appreciate her honesty about her health struggles and her open affection for her brother.

Heo Sol-ji commands a substantial global audience, recognized primarily through the enduring legacy of EXID and her established solo career as a vocal powerhouse. Her influence spans decades, from the group's historic reverse run to her recent work in musical theater and television judging. Despite this significant footprint, iFANN's Global Fame Engine has evaluated Heo Sol-ji but currently does not assign her a placement within the published Global Top 1,000 or any Top-100 scope list. While she remains a household name in South Korea and among dedicated K-pop circles worldwide, she does not hold a specific numeric rank in the current global hierarchy. The fanbase supporting Heo Sol-ji is formally known as Legs, though some sources also refer to them as Lega. This collective organization has demonstrated remarkable influence, particularly during the group's rise to fame with "Up & Down," driving chart success through organized streaming and album purchases. While there is no documented sub-fandom name exclusively for Solji, her personal interactions with Legs are frequent and warm, often highlighted by her gratitude posts on social media. Fans have witnessed her resilience firsthand, from her recovery after orbital decompression surgery in 2018 to her emotional vulnerability during rehearsals for "Six The Musical." These shared moments have deepened the bond between the vocalist and her supporters without creating a separate, formalized identity distinct from the group's overarching fandom.[edit]

Solji shares an famously close bond with her older brother, who described their connection as being able to "die for each other" and called one another "my other half" in a December 2022 SBS Star segment. Before her idol debut, she honed an analytical ear working as a vocal trainer, a skill that allows fans to witness her impressive ability to sight-read music and master harmonies instantly. She maintains a soft spot for trot music, a genre she frequently explores while serving as a judge on "The King of Strings 3." A story fans still retell involves her daily tears during rehearsals for "Six The Musical" in May 2023, where she admitted to crying every day, showcasing an intensity that resonated deeply with critics and supporters alike. Her journey also includes a pivotal health chapter in January 2018 when she underwent orbital decompression surgery, followed by a playful reunion with EXID in the "I Love You" music video later that year. Her solo debut mini-album, First Letter, released in February 2022, marked a definitive step in establishing her individual artistic voice alongside her group achievements.[edit]

Solji has an older brother, though his name has not been made public. The two share an exceptionally close relationship, which she described on SBS in December 2022 as being like "my other half." She has said they would do anything for each other, and the segment highlighted how they support one another through the demands of her career.

Details about her parents and extended family have not been shared publicly. She keeps her household private, and no information about pets or her current living situation is available. [edit]

Solji is closely associated with her EXID bandmates: Hyo-jin Ahn (LE), Hye-lin Seo (Hyelin), Park Jeong-hwa (Jeonghwa), and Ahn Hee-yeon (Hani). She also works alongside fellow judges Hong Ji-yoon, Cha Ji-yeon, Lee Soo-yeon, Koo Soo-kyung, and Kang Hye-yeon on "The King of Strings 3." Her older brother, though not publicly named, is a significant figure in her life. [edit]

Solji has kept her romantic life entirely private. No public relationships, engagements, or marriages have ever been documented. As of 2026, she is reportedly single, with no credible sources confirming a partner. The only close relationship she has openly discussed is with her older brother, whom she called "my other half" on SBS in 2022. [edit]

iFANN currently estimates Heo Sol-ji's net worth at $6 Million in 2026. This financial standing stems from a diverse portfolio built over a long-running career. Her primary income flows from her tenure as leader and main vocalist of EXID, encompassing album sales, concert tours, and endorsement deals. Additional revenue comes from her expanding solo activities, notably her first solo concert titled "Our Memory" announced in August 2025. Her role as a judge on "The King of Strings 3" further diversifies her earnings through television appearances. The foundation laid during her early years as a vocal trainer continues to support her financially through music royalties and substantial YouTube revenue, which has accumulated over 46 million views across her channel. Her consistent presence in the industry since 2006 and active engagement in 2026 reflect a stable and growing economic position.[edit]
