Govinda had recently criticised David for not standing by him during hard times.
"I have not heard it," Varun said when asked about what he has to say about the remarks made by Govinda on his father.
When the journalist said 'should I tell you Govinda's remarks,' he said, "I can't hear anything."
Govinda had said that the filmmaker did not stand by him when he was going through a bad phase and did not take him in any of his upcoming films despite requesting him several times.
Govinda is looking forward to the release of "Aa Gaya Hero" which is slated to release on March 3.
