Actor-filmmaker Aamir Khan, who is turning 50 on Saturday, says he is not aware of his birthday plans as his wife Kiran Rao is making all the arrangements.

"I am not aware of my birthday plans, only Kiran knows as she is planning for it. She has made all the arrangements," Aamir told reporters here on Wednesday at the DVD launch of his film "PK".

"She has called family and few friends. I don't even know who she has called," he added.
