There has been speculation whether Kajol will accompany co-star Shah Rukh Khan to promote their film, 'Dilwale', on the Salman Khan-hosted reality show, 'Bigg Boss 9'.

SRK is slated to feature on the show this weekend. If the grapevine is to be believed, Sallu and Kajol are not exactly pals.

They featured together in the 1998 film, 'Pyaar Kiya To Darna Kya', during which they apparently had differences. Post that Sallu did a cameo in the SRK-Kajol starrer, 'Kuch Kuch Hota Hai' (1988), but after that they were not seen together in any film.
