In the first, Aamir is seen in a long moustache, Tony Stark-ish beard and weird headgear. While some reports suggested that this is from the Lagaan ride at a Bollywood theme park in Dubai, others think this is the actor's look in new film Secret Superstar.
Have a look:
The second one has Aamir dressed in a multi-coloured body-hugging tee, bling belt and denims. Aamir also sports a sharp beard and moustache with highlighted hair, gelled to defy gravity.
Apparently, this is how Aamir will look in the new film which will be directed by his former manager Advait Chandan.
Aamir Khan, who will be producing the project, is said to have a cameo in the film.
Aamir was recently spotted at the announcement of the Global Citizen Festival with actors Amitabh Bachchan, Farhan Akhtar and Kareena Kapoor Khan.
Aamir Khan, who hasn't appeared onscreen since 2014's PK, will next be seen playing wrestler Mahavir Singh Phogat in Dangal, which will hit screens on December 23.
