Actress Katrina Kaif may have worked with some of the biggest names in Bollywood including Amitabh Bachchan, Salman Khan and Akshay Kumar but she says that her latest co-star, Ranbir Kapoor, was great to work with because he does not have an ego problem.

The actress who is paired opposite the 'Saawariya' actor in the upcoming romantic comedy 'Ajab Prem Ki Gazab Kahani' said that she had fun on the sets, thanks to Ranbir.

"I was kind of chilled out and had fun while shooting with Ranbir. He is a great co-star who is passionate about his work and does not have an ego," said Kaif.

'Ajab Prem Ki Ghazab Kahani', a romantic-comedy starring Ranbir, Katrina and Upen Patel also has a special appearance by superstar Salman Khan.

Talking about the film produced by Ramesh S Taurani and directed by Rajkumar Santoshi, Kaif said, "It is a romantic-comedy. Though hundreds of movies have been made on love but this is unsual, it is unique, wacky and stylish."

The movie will hit the silver screen on November 6.
