Shah rukh Khan, who is busy promoting his upcoming film ‘Zero’, co-starring Katrina Kaif and Anushka Sharma, recently went to promote his film on the sets of Salman Khan’s show ‘Bigg Boss 12’. Both of them had a gala time at the show as they danced on ‘Issaqbaazi’ from ‘Zero’, which sees the bromance of Salman and SRK.
