Mumbai: Shahrukh Khan will promote 'Ra.One' in 'Bigg Boss 5' co-hosted by his arch rival Salman Khan and Sanjay Dutt.

As part of Shahrukh Khan's publicity blitzkrieg for Ra.One, the star will make his way to the Salman Khan-Sanjay Dutt hosted reality show to promote his film. But before you start getting excited about the big clash of the dushmans on the small screen, hold on. Dutt will be hosting several episodes of the show solo, that's when SRK will be in the house!

Salman is currently in Dublin for Ek Tha Tiger. As reported in Hitlist, October 4, the star left on Sunday night. He will not be present for the first eviction from the reality show this Saturday, which will be anchored by Dutt alone.

Says a source, "Salman is slated to be back at a later date, so he will be missing from the first eviction from the house. When Salman is tied up with his film shooting or medical treatment, Dutt will be hosting it."

As SRK is on an overdrive promoting his flick on TV shows, he is slated to be make an entry in the house too. Adds the source, "The makers feel as the contestants are all females, it would be great to have Shahrukh enter the house as a guest to promote his film."
