Alright, Amitabh Bachchan is hosting 'Kaun Banega Crorepati 4' on Sony. The moment this was out, one anticipated rival channels to chase other big superstars of Bollywood. Most of Bollywood's big wigs sans Aamir Khan have made their television debut.

As Big B returns again to TV, there is talk in the media circle that Shah Rukh Khan will be chased by rival channels.

It didn't take long for speculation to ripe as King Khan is said to be hosting the fourth season of 'Bigg Boss', so claims a news channel.

This channel aired this news day before yesterday and was pretty confident about their story. According to their report, Shah Rukh Khan has all but signed for 'Bigg Boss 4'. The show is said to commence from October 3.

It's no secret that Shah Rukh Khan is close friend of the owner of this channel.

Neither Colors nor Endemol India will talk about 'Bigg Boss' now, as they first have the burden of 'Fear Factor' on their shoulders.

We wonder whether Shah Rukh will really be comfortable taking up a show where he would again be accused of following Bachchan's footsteps.

Speculation over the contestants has begun too. Sara Khan of 'Bidaai' is tipped to be the first contestant.

Well, the speculative missiles have just been fired. There's no stopping them now. Expect more probable hosts or contestants in the coming days.
