“It is with deep regret that we impart the heartbreaking news,” said Production Ogi, which managed Goo’s gigs in Japan.

A private wake will be held at Gangnam Severance Hospital per the family’s wishes, the agency said. The public is asked not to visit.

A separate public memorial will be held at Seoul St. Mary’s Hospital in Seocho, southern Seoul, from 3 p.m. Monday to Wednesday at midnight for fans to pay respects to the late star.

In May, Goo was hospitalized after an apparent suicide attempt. Upon recovery, she issued a statement via her agency apologizing for “all the trouble.”

Last year, Goo was involved in a highly publicized legal battle with former boyfriend Choi Jong-bum, a 28-year-old hairdresser, who threatened to release a sex video to media.

While Choi has denied actually releasing the footage, an online entertainment outlet revealed Choi reached out to the outlet saying he had a “tip-off” about Goo. In CCTV footage revealed by the said outlet, Goo is seen kneeling before Choi reportedly begging him not to release the video.

In August, Choi was given a suspended sentence for intimidation, assault and property damage, among other offenses. He was found not guilty of filming and blackmailing her. Both the prosecution and Choi appealed the ruling.

Goo debuted in July 2008, joining girl group Kara, and quickly rose to fame. Since leaving Kara in 2016, Goo pursued a solo career in Japan.

Singer-actress Sulli, who was found dead Oct. 14, was Goo’s close friend.
