Major hallyu star Choi Ji-woo collapsed from overexertion on the afternoon of July 6 in her apartment. She lost consciousness for a moment and was rushed to a nearby hospital. The actress was released on the morning of July 7 and is currently resting at home.

`She has been very busy lately, shooting videos in five countries and holding the `Drama Concert` in Japan last month. She was also expected to star in a Japanese television drama. Such a hectic schedule has apparently wreaked havoc on her health,` said a person close to Choi.

As a result, Choi was unable to participate in neither a press conference nor a reception marking the year of Korea-Japan friendship that were held on July 7 at the Tokyo Okura Hotel under the auspices of the Korea National Tourism Organization.
