Vivian Hsu is reportedly 4 months pregnant and was hospitalised for stomach problem recently.
She was bed-ridden after that and needed a wheelchair for daily activities.
According a news report, Hsu might have complications giving birth due to her age. She also risked experiencing a miscarrriage, reported Asian E-News Portal.
Hence, it was rumoured she might have undergone a womb-related surgery last month.
After the operation, Hsu apparantly could not handle the weight of the baby and had to stay in bed until the baby is born.
