SalKat were shooting in the same premises for almost the entire day but didn't even bother to go say hello to each other. The air in Mehboob was rife with tension with people speculating what would happen when Khan and Kat stepped outside their vans and bumped into each other."
Both Sallu's and Kat's sentries (read staff) were posted outside the vanity vans to alert them about the movements of the other.
Continues the source, "It wasn't just the ex-lovers who kept their distance, even Salman's one time protege Hrithik didn't drop in on Khan's set to greet him. The last time, they were in Mehboob, (when Duggu was shooting for Guzaarish) Salman had gone to Roshan Jr's van and chatted with him.
