Abhishek Bachchan and Aishwarya Rai Bachchan did it in the past. They announced their wedding just a few days before the release of their film, Guru. The news created more curiosity among the public and the film went on to become a big hit. Riteish and Genelia are also likely to make their wedding announcement on the day Tere Naal Love Ho Gaya releases early 2012.
Producer of the film Kumar Taurani revealed that their real-life friendship must be the reason for their great chemistry in the film, though he didn't get into the coincidence of his film's release and their wedding!
