Is Sidharth Malhotra Not Invited to Varun Dhawans Wedding?

With all the news and articles going on about Varun-Natashas wedding, I didn't see or read any news about Sidharth Malhotra being invited. Why is that? They both debuted together in SOTY years ago, and they seemed like they were good friends then. So what happened after that turned their friendship sour? They acted well together in SOTY, after that Varuns career took off and Sidharts was a little slow, maybe the competition got to them?
