It's a known fact that Salman Khan and Aamir Khan are the best of friends in B-town and the duo share a great bond.

And in a recent episode of the controversial show Bigg Boss 7, Salman promoted Aamir's upcoming film "Dhoom 3". Salman, who hosts the show, was seen wearing Aamir's signature bowler hat from "Dhoom 3".

Aamir started wearing the hat from last year onwards to get comfortable with it and it now looks like the actor doesn't want to leave it. Aamir is seen wearing the hat with all types of attire, be it formal casual or traditional.

The "Dhoom 3" actor has recently said that he would not be promoting his film on television, reality shows, events or public places.

"Also, Aamir informs me, he won't be doing rounds of TV shows or visiting malls of cities to promote #Dhoom3. Wants trailers to do the trick," trade analyst Taran Adarsh said.

But it seems Salman is putting in his best effort to promote his dear friend's film.

"Dhoom 3" is the third film in the "Dhoom" franchise. The film also stars Katrina Kaif, Abhishek Bachchan, Jackie Shroff and Uday Chopra.

The much-awaited film of the year is expected to create records at the box office. The hype surrounding the film is very positive but it is not sure whether it will reflect on its box office earnings.
