Priyanka Chopra

For Valentine's Day, actress Priyanka Chopra urged people to pledge to donate their heart for a cause.

On Tuesday, Priyanka tweeted: "Make this February 14 special, pledge to be a Valentine for a cause... Donate your heart. My heart," Priyanka tweeted.

Saif Ali Khan, who is gearing up for the release of his forthcoming film "Rangoon", also said in a video: "This Valentine's Day pledge to make a difference... Donate your organ for a great cause."

The messages are in support of news network NDTV's campaign #MyHeart in association with an organisation called MOHAN Foundation.
