Singh was reacting to "speculation" that Priyanka had taken Aishwarya's place in Chandraprakash Dwivedi's "Prithviraj Samyukta" after the filmmaker gave up the wait for her.
"I would like to reserve my comments on Dwivedi's film, since we are in talks with him for a project but Aishwarya is the last to be affected by such news. I wish Priyanka the best of luck in her endeavour but Ash needn't worry about people replacing her.
"In fact, she's got a record number of period films lined up from 'Jodha Akbar' to 'Umrao Jaan' and Ketan Mehta's 'Jhansi Ki Rani'."
However, he admits she was upset with the makers of "Bluffmaster" when Priyanka replaced her in the film without her knowledge. Priyanka has taken Aishwarya's place in three films so far - "Bluffmaster", "Krrish" and "Sahib Biwi Aur Ghulam".
