Katrina is More happy to Worked with ranbir

Katrina is all the more happy to have worked with Ranbir and also finds it bit relaxing. Smiles and says the pretty damsel, ''Till date whenever I reported on the sets of any of my films, I was accustomed to saying good morning sir! Thank God! While working in AJAB PREM I never had to do anything like that. Jokes apart, when you work with the people of same age-group, you automatically get comfortable. Ranbir is a chilled out guy, never takes himself seriously and doesn't have any ego problems. So it was very easy and natural to get along with him.''
