Chak Dhoom Dhoom is back with its second season and this time a lot is changing on this dance reality show. A source says, “Mallika Sherawat, Terence Lewis and Javed Jaffery will be judging the show this season. The show will once again be hosted by Pravesh Rana. The pattern will be different as it will be a group challenge and not an individual performance. Hence, one will get to see group performances. The show is most likely to go on air by mid-January but a final date hasn’t been locked in yet.” So will the show follow Bigg Boss 4? The source says, “No, it won’t take off just after Bigg Boss wraps up as the latter gets over on January 8. This will take off in mid-January. The show will be aired on Fridays and Saturdays.” Terence confirmed his participation and that of his co-judges too and said, “I am very excited as it’s going to be teams and groups this time with no age bar. At present I am auditioning for the same at Baroda.” Javed Jaffery confirmed his participation too and said, "Yes, I am judging it and looking forward to it." Rana remained unavailable for comment.
