Buzz has it that Ranbir and Deepika were supposed to grace Tarun Mansukhani's birthday bash. However, due to Deepika's work commitments, she was unable to attend the event and the duo decided that Ranbir would go alone. The hot hunk did go to a party but not Tarun's birthday party. Instead of attending Tarun's birthday bash, Ranbir went to another party with debut co-star, Sonam Kapoor and good friend, Kunal Kapoor. On the other hand, Deepika was unaware of the plan change. When she found out, she called Ranbir and simply lashed out at him and accused him of lying! Meanwhile poor Ranbir was giving her excuses for the plan change!
Looks like another B-Town couple heading towards disaster!
