Considered to be an enfant terrible a few years ago, Salman Khan is a totally changed man today. Believing in giving out a lot by way of charity, the Tere Naam actor is a true friend to whomever he considers one and does all he can for him/her in times of need. As a matter of fact, he goes out of his way to help his friends. A similar thing happened when Aamir Khan was called over to the sets of Bigg Boss season 7 (Colors) to promote his upcoming YRF film Dhoom 3. And knowing well that his good friend Aamir refused to promote his film on television, Salman took it upon himself to promote the project indirectly by donning the hat Aamir wore in the film in his show. Interestingly, Aamir started wearing the bowler hat last year when shooting for Dhoom 3 to get comfortable with the look. While promoting the film, the star was spotted wearing a similar hat.
