Why was Salman Khan missing at Sridevi's bash?

Now everyone in B-Town knows that the star had a fallout with Walia, who was his best buddy once. In 2011, at a bash hosted by Sanjay Dutt for his wife Maanayata's birthday, Sallu is said to have had a verbal spat with Walia. Sallu's brother Sohail and Bunty were business partners till they went their seperate ways. Looks like Sallu is in no mood to forget or forgive.
