Hyderabad: 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".
