Taiwanese star Barbie Hsu, who was hugely popular across Asia for her leading role in the 2001 television drama "Meteor Garden", died from a respiratory illness, media reported Monday. She was 48.

Hsu passed away after developing pneumonia during a family trip to Japan over the Lunar New Year holiday, the younger of her two sisters was quoted as saying.

"My dearest and kindest sister Barbie Hsu sadly left us due to influenza complications that led to pneumonia," the younger Hsu said in a statement shared by her agent and reported by the Central News Agency.

"I'm grateful to have been her sister in this lifetime, to take care of each other, accompany each other, I will forever be thankful to her and miss her."

Hsu's death was the top trending topic on Weibo on Monday.

Fans around Asia and elsewhere also paid tribute to her on social media.

Actor Huang Xiaoming, who starred with Hsu in another drama, said he was "in shock and deep grief" over her death.

"I've heard that truly brilliant souls are never dimmed by time -- they remain vibrant, like bubbles shining in the sun," Huang said on Weibo.

Stacy Hsu, a Taiwanese celebrity, posted on Facebook that Hsu's "beauty and intelligence will forever remain in our hearts."

Hsu and her younger sister Dee rose to fame in the 1990s as a pop duo before switching to hosting TV shows and acting.
