Ranbir Kapoor has denied rumours of Katrina Kaif addressing his father as "papa" at a party. It was reported that Ranbir's girlfriend Katrina was overheard calling Rishi Kapoor as "papa" at a party.

However, Ranbir is not ready to believe the buzz as he said, "No, it is not true. She doesn't call him Papa. She calls him Rishiji," Miss Malini.com quoted Katrina's boyfriend as saying with a smile on his face.

Earlier, Times of India quoted a source at the party as saying, "One hears that at a recent party that Kat and RK attended, the actress very sweetly pecked Rishi Kapoor on his cheek and asked him, 'Hi papa, how are you?."

Ranbir and Katrina's relationship has been one of the most talked about topics in tinsel town and often rumours of their soon-to-be-held marriage also pop up.

Although, both Ranbir and Katrina have given enough hints which prove that they are in a relationship, the duo has never admitted it in public till date.

It was also reported that Ranbir has moved out of his parents' house and the couple are staying together at a separate flat in Mumbai.
