It was working birthday for Ranbir Kapoor who turned 34 this Wednesday. The actor spent the day filming Jagga Jasoos with ex-girlfriend and co-star Katrina Kaif. Post 10 pm, it was all about celebrations for RK as close friends Arjun Kapoor and Aditya Roy Kapur surprised the birthday boy with a football-shaped cake. Conspicuously missing from the party was Katrina. According to a leading website, Kat left long before the celebrations began. The actress wrapped up before Ranbir and chose to skip his party to avoid any awkward encounter. However, Katrina stopped to wish her ex before leaving.
