The pain was so severe that the paramedics were called onboard and the couple had to board off. Vidya was later taken to Mumbai where she was admitted to the Hinduja Hospital in Mumbai's Khar area.
"Vidya is recovering well. She is feeling better. Most probably, she will get discharged by January 1," said a source close to the actress.
Vidya had planned to celebrate the New Year with her husband Siddharth Roy Kapur abroad, but they had to cancel their outing as she suffered excruciating pain. (Also Read: Vidya Balan Hospitalised For Suspected Kidney Stone)
