Photos of local singer Stefanie Sun collapsing onto a wheelchair and carried by crew members when she got off stage after her concert in Chongqing, China on June 22, 2014, have been circulating online.
She was later sent to the hospital and put on a drip as she has reportedly been feeling unwell since June 11 but insisted on continuing with her Kepler world tour.
On 11 June, she posted on Weibo saying that she was suffering from a serious flu for 5 days.
However, Sun showed no signs of illness during her concert where she sang and danced to 30 songs for a 50,000-strong crowd.
The 35-year-old has since posted on Weibo after the concert talking about her condition.
She wrote: "Chongqing, I've lost my voice... Haha."
And by Monday, she took to her micro blog again to let her fans know she is fine.
"After sleeping for an entire day, I have recovered!"
"I hadn't completely recovered from the flu at the time, so I didn't manage to exit the stage perfectly and made everyone worry."
"Today, I can return to Singapore to see the baby! Happy."
Sun will be the first popular act to perform at the newly opened Singapore National Stadium on July 5. This will be her first major concert here since she went on hiatus about three years ago. Before her three-year hiatus, she took a four-year break from releasing an album previously.
