Krishna Raj Kapoor, wife of legendary actor Raj Kapoor, passed away Monday due to cardiac arrest.

She was 87.

"My mother passed away at about 5 am today due to cardiac arrest...old age was another factor. We are deeply saddened by her demise," son Randhir told PTI.

In May 1946, Raj Kapoor married Krishna Malhotra and the couple had five children --three sons, Randhir, Rishi and Rajiv, and two daughters, Ritu and Rima.

The last rites will be performed at Chembur crematorium, Randhir said.

Trade analyst and well known film critic offered his condolences to the family. Besides him, condolences have been pouring in from celebrities and fans of the Kapoor family, here's a look
