"He has been admitted to hospital," the sources told PTI without disclosing as to when and for what reason the veteran filmmaker has been admitted.
The 80-year-old filmmaker had announced his retirement from film direction last month.
He is looking forward to the release of his latest directorial venture 'Jab Tak Hai Jaan' that stars Shahrukh Khan, Katrina Kaif and Anushka Sharma in the lead.
The film is set to hit the screens on November 13. Chopra has given several hits in his more than five decade old career such as 'Deewar', 'Kabhie Kabhie', 'Trishul', 'Silsila', 'Chandni' and 'Veer Zaara'.
