Five things we don't know about Mr. PERFECTIONIST!

3. He can't bare loud music

The reason he's not seen at many film parties -- or why he retires to a separate Aamir-and-friends room when he's at one -- Aamir explained, is because he hates loud music.

Karan Johar felt Aamir was the industry's biggest party-pooper, either retiring to a different room at a party or inviting the guests at that party over instead to his home! Candid as ever, Aamir said he had turned down invitations to appear on earlier incarnations of KWK because he didn't like Karan then.

When the host gingerly inquired if Aamir had changed his opinion since, the star hummed and said he liked Karan now and had probably changed himself as well.
