S.H.E member Selina Jen has announced her divorce from lawyer Richard Chang, 43, in a post on her Facebook at 11am on Friday (March 4).
By 1.50am, the post had attracted more than 47,000 shares and more than 30,000 wows.
Jen wrote in Chinese that a marriage requires the effort of two and admitted that the couple, who married on Oct 31, 2011, "have not done enough".
She said she has not played her role as a wife well because she still focused on her work after getting married.
She admitted that there has been "a big change" in her life perspective before and after marriage. She no longer wholeheartedly lives for love, which is why their love has gradually disappeared, she wrote.
She added that they were unhappy as husband and wife- "problems that existed still plagued" them and "there is no way to change ourselves or each other".
Jen called the decision to end the five-year marriage "necessary".
"Because we've lost love, so we don't want to lose kinship and friendship as well."
Mr Chang also shared his thoughts on his Facebook, saying they are "happier being siblings".
"In this broken marriage, I lost a wife but gained a sister who is closer to me than my own sister.
"Please don't feel sorry for us. We are happier being siblings."
The announcement came as a surprise because Mr Chang has been shown as Selina's pillar of support in media reports, particularly after a near-death experience for Selina.
In October 2010, while filming the television drama I Have A Date With Spring, Selina was badly hurt in an accident involving explosives which left her with burns - some as severe as third-degree on her back, limbs and waist - around 50 per cent of her body.
Mr Chang even published a book documenting her long road to recovery.
In April last year, Jen's S.H.E bandmate Ella Chen was quoted saying the couple was trying for a baby.
That same year, Mr Chang was photographed by Taiwanese paparazzi hanging out at a KTV lounge with a young woman. It sparked off rumours that the couple's marriage was on the rocks.
