Suddenly the noisy festive bustle went quiet and Zoya announced it was Katrina's birthday. Everyone was ordered to sing 'Happy Birthday' to Katrina. Recalling the emotional moment with great pleasure Katrina says, "Suddenly there were 500 people Spanish, Indian and every nationality you can imagine, on this main street of Pamplona singing 'Happy Birthday' to me. It was an awesome moment and the best birthday gift I've ever had. It was very considerate of Zoya to arrange this surprise for me."
The whole cast was shooting together in Spain for Zoya Akhtar's Zindagi Na Milegi Dobara by participating in one of Spain's biggest festive events, the Encierro, or Running Of The Bulls festival. Expains a source, "Since Zoya's film is set in Spain the first thing that came to the team's mind was a bullfight. But they all thought that was too predictable. So they hit upon the Running Of The Bulls festival.
