Bachchan, 73, and Aamir will share the screen space for the first time in the movie Thugs of Hindostan, to be directed by Dhoom 3 helmer Vijay Krishna Acharya (Victor).
The 51-year-old actor said he is excited to work with his icon, whom he has admired all his life.
"Finally, the moment I have been waiting for has come... To work with my icon, Mr Bachchan! Thanks, Adi, Victor, for Thugs of Hindostan. I'm too thrilled to be working with the actor I have admired all my life," Aamir posted on Twitter.
The actor, who is geared up for the release of biopic Dangal which features him in the lead role of Mahavir Singh Phogat, will start shooting for the YRF project early next year. The leading lady of the film is yet to be announced soon.
Thugs of Hindostan is slated to release on Diwali 2018.
