On whose failure did Bunny celebrate?

Allu Arjun’s over enthusiasm at Julayi audio function had made him point of discussion in Tollywood. Speaking at the event, he made an interesting revelation. He said, “It is quite general, we heroes feel insecure with the success of other heroes. We often take them as challenge and work hard to do better than him. Recently, I enjoyed a lot when a hero’s movie failed. Then Babai called me and asked why. I said I hate that fellow and I wished for that movie to fail. Then he said that is a big mistake, there are many people who live on that film”.
Interesting question in this entire episode is who is that hero Bunny hates? Any Guesses?
