Kangana Ranaut attended the special screening of 'Thithi' couple of days ago looking visibly stressed.

A source says,"Though Kangana posed for cameras and attended the screening, she seemed bit tired. She even skipped interacting with the media present at the cinema hall."

Adds the source, "When media people called out to her and asked questions, she stopped them and told them that she will come back and speak to them post the film gets over. But she left the venue as soon as the screening was over and did not stop for a minute, which surprised everyone."
