Oscar winning composer A.R. Rahman says he was “devastated” after hearing about Bollywood singer-composer Aadesh Shrivastava’s struggle against cancer.

Shrivastava, whose cancer has relapsed for the third time, is undergoing treatment at Kokilaben Dhirubhai Ambani Hospital & Medical Research Institute in Mumbai, India since the last 45 days.

“Dear buddy Aadesh, I am devastated at hearing about your condition ... Can’t come to terms with it. May god help you ease your pain,” Rahman tweeted on Friday.

Shrivastava has composed music for films such as Chalte Chalte, Baabul, Baghban, Kabhi Khushi Kabhie Gham and Raajneeti, among others. He is married to actress and playback singer Vijayata Pandit.

Legendary singer Lata Mangeshkar also tweeted saying she is praying for Shrivastava’s fast recovery.
