That seems to be the buzz making rounds. Apparently, the gorgeous beauty Aishwarya Bachchan celebrated her birthday recently and as usual, the film stars of Bollywood were asked to give their wishes to a noted channel. While Ranbir Kapoor is said to have obliged and wished her, the media was said to be surprised when his co-star Katrina Kaif dodged by stating that Ranbir has already given it. Members also say that after the interview, Kats rushed to her vanity van and didn't come out for quite a while. Hard to believe this one...
