The 37-year-old actress was admitted to a suburban hospital post Diwali and chose to remain there for some more time.
Earlier, reportedly, due to some minor complication, Rani was admitted to Hinduja hospital in suburban Khar.
"She is in the hospital and will be there for few days as work is going on at her house... So her stay in the hospital has been extended," sources said.
"She is fine. She is still in hospital and resting," they said.
