A special song in the upcoming Om Shanti Om features Bollywood's biggest names, with 31 stars agreeing to be a part of the memorable song sequence, including stars like Salman Khan, Sanjay Dutt, Saif Ali Khan and Mithun Chakraborty, who flew down from Hyderabad just for the song.

Now, Rediff.com takes a look at the four actors who turned Khan down:

Aamir Khan

They are traditional rivals. When Shah Rukh entered the film industry, it was already dominated by the other two Khans, Salman and Aamir.

Shah Rukh however took them by surprise and went on to become the superstar. He not only displaced the other two Khans, and proved that at the box office every year -- his films made the maximum moolah at the box office.

Though Salman has acted in three films with SRK -- Karan Arjun, Kuch Kuch Hota Hai and Hum Tumhare Hai Sanam -- Aamir has not yet shared screen-space with King Khan.

When Shah Rukh invited Aamir for the song, he simply said he was out of station, so could not come for the shoot.
