Imran Khan, 31, tied the knot with his childhood sweetheart Avantika in 2011 in a private ceremony.
"At this point there is more frustration level with the baby being inside for many months. She (Avantika) is getting bigger, her feet are swollen, her back is aching and so she is getting cranky.
"She wants to get it out. There is no excitement. There is frustration now. Her health is fine but she is not happy," he said.
Imran Khan, who is said to be on a break from showbiz to take care of his heavily pregnant wife, said his family is his utmost priority.
"I have always taken my responsibility towards my family very seriously. For me family still comes first," Imran Khan said.
