"Aamir is a living legend. He has a beautiful mind and he definitely is one of the finest actors of all time," Kareena said during India's Prime Icon programme.
The actor is competing with the likes of Amitabh Bachchan, Sachin Tendulkar, A.R. Rahman and Narendra Modi for the title of "India's Prime Icon".
Kareena's elder sister Karisma Kapoor, who has worked with Aamir in "Raja Hindustani", also heaped praise at the actor.
"Aamir is most definitely an icon and a true legend. He is always up to something new and different. I've had the opportunity of working with him in iconic films like 'Raja Hindustani' and 'Andaaz Apna Apna'," Karisma said.
"I'm really happy that after 'Talaash' and '3 Idiots' even Kareena-Aamir jodi has become a hit pair," she added.
