Bollywood's 'Mr. Perfectionist' Aamir Khan accepts he has undergone a lot of transformation over the past few years, thanks to his filmmaker wife Kiran Rao.

"Transformation has happened. I feel it is because of Kiran-ji. Her influence on me is very bright," the 49-year-old said here in an interview.

"Her energy is bright. So, a change has come in me as well," he added.

Aamir married Kiran in 2005 and together they raise a son named Azad Rao Khan, whom they had via surrogacy. The two met during the filming of Ashutosh Gowariker's "Lagaan".

Currently, Aamir is busy promoting his film "PK", which will hit the theatres Dec 19.
