Vivek Oberoi, who will be seen as as one of the leads in forthcoming adult comedy "Grand Masti", was initially nervous about the audience's response to the film's promos, but heaved a sigh of relief after getting overwhelming response.

"Since we have made the film ('Grand Masti'), so we were very nervous...whether the audience will like the film or not, whether they will like the promo or not...," Vivek told reporters here Monday at the film's music launch.

"But when saw the reactions for the promo (of 'Grand Masti') and how people downloaded it on Whatsapp and exchanged it among them...I was enjoying it. Even we were watching the promo sitting in office.

"We were getting calls from everywhere. People are watching it together in trains also. So that's just people's verdict and we are very, very fortunate with the way the promo is being received," he added.

A sequel to "Masti", "Grand Masti" will see Vivek teaming up with Riteish Deshmukh and Aftab Shivdasani. The trio were in the cast of 2004 release.

Directed by Indra Kumar, "Grand Masti" also features Sonalee Kulkarni, Maryam Zakaria, Manjari Phadnis, Bruna Abdullah, Kainaat Arora and Karishma Tanna.

It is slated for a Sep 13 release.
