The actor was promoting his upcoming movie "Besharam" when a reporter at the event asked what did Katrina gift him on his birthday, which was on September 28.
"There is a phrase in English 'Mind your own business'," Ranbir Kapoor replied.
The 'Barfi!' actor and Katrina Kaif recently made headlines when
their pictures while holidaying together in Spain were published.
There were reports that the duo will go on a holiday again, but Ranbir Kapoor chose to keep mum on this too.
"When pictures get published, you only inform... What should I say," he said.
