Bipasha Basu is coming to CID for promotion of Raaz 3
Guest appearance in TV serials or reality show or talk show is the best way to promote upcoming movies. Because by appearing in these daily things, you directly connect to the audience and hence your movie can get the good start.
Like Kareena and Ranbir are coming to Indian Idol 6 finale for promoting their respective upcoming movies. Heroine (see trailer) and Barfi.
