Made at Rs.35 crore, it has been written by Milap Zaveri and has earned brickbats from critics for innuendos and suggestive leery double-meaning dialogues.
But Vivek, whose movies like "Prince" and "Mission Istanbul" bombed at the box office, is undeterred by the criticism and wants to enjoy the success that has come to him after a long while.
"Party! Milap. After a humungous start, 'Grand Masti' (earned) even better than Friday on Saturday with Rs.13.5 crore! Grand total is now Rs.26 crore in just two days!"," Vivek posted on Twitter.
"Missing @Riteishd my darling 'Masti-Khor', wish you were here to party and celebrate with us bhauuu! Incomplete without you man! Come back na! (sic)," Vivek tweeted.
The film's success is a good news for Aftab too.
"Been such an eventful Friday and Saturday! Completely elated and overwhelmed by the response," he posted on the micro-blogging site.
