SEOUL • Fans of K-pop singer HyunA may have to wait a little longer for her first studio album.

The 28-year-old singer was originally planning to launch her pre-release single, Good Girl, on Wednesday, ahead of her full studio album later this year.

But the release of the single has been put on hold as a result of fainting spells suffered by HyunA, who made her debut with girl group Wonder Girls in 2007. She is also a former member of girl group 4Minute.

Last Saturday, her agency P-Nation said: “It is with regret that the release of HyunA’s Good Girl has been postponed to a later date due to her ongoing medical condition (vasovagal syncope).”

The agency, which was founded by South Korean singer Psy, added: “At this time, we will focus on providing HyunA with the medical attention she needs and be with her through every step of her recovery process.”

Vasovagal syncope is a type of fainting spell caused by a fall in blood pressure due to dehydration or standing for too long.

HyunA, who is known globally for her appearance in the music video for Psy’s 2012 worldwide hit Gangnam Style, disclosed in November last year that she suffered from depression, panic disorders and vasovagal syncope.

The revelation came after the deaths of singers Sulli last October and Goo Hara last November.

HyunA had also released Flower Shower, her first single with P-Nation, in November last year.

She left her long-time label Cube Entertainment after going public with her rapper boyfriend Dawn, formerly of boy band Pentagon, in 2018.
