Two women in South Korean show business have been warded in hospital, with one linked to a suicide attempt.

Former television entertainer Amy was devastated after Monday's episode of Channel A's variety talk show, I Heard It Through The Grapevine, featured issues and rumours about her past.

The Korean-American, who debuted as a TV actress in South Korea in 2008, was found guilty of drug offences in 2012 and 2014 and was ordered to leave the country in 2015. She has been living in the United States since.

Following the broadcast, she reportedly attempted suicide at her Los Angeles home on Tuesday. According to the Korea Herald, she wrote on Instagram: "I am so tired now. I have nowhere to fall. I want to go somewhere I don't feel sad."

The Grapevine producers have apologised, saying: "We accept that the episode hurt Amy. We wish her a fast recovery."

South Korean media also reported on Wednesday that actress Shim Eun Ha, who was popular in the 1990s, was taken to a hospital after apparently overdosing on sleeping pills. "It is true Shim is hospitalised," a hospital official said. "But the specific reason cannot be disclosed since it is personal information."

The hospital confirmed that she was not in critical condition. Shim has rarely appeared in public since she married a lawmaker in 2005.
