Actor Vivek Oberoi, whose relations with Salman Khan soured some years back, has refused to comment on why he avoided meeting the superstar on the sets of his upcoming film "Great Grand Masti".

Salman was recently at the Mehboob Studio for a promotional event of his recent release "Prem Ratan Dhan Payo". Post the event, the "Bajrangi Bhaijaan" star reportedly met director Indra Kumar, who took him to the vanity van where all the lead actors of "Great Grand Masti", including Vivek, were present.
