In the latest on the duo, they were spotted sharing a kiss on board an international flight on Sunday from Frankfurt to Mumbai.
Reports say the two were seated side-by-side in the first class of the flight and after making sure that no one around was paying attention to them, they cosied up to each other and Ranbir even planted a kiss on Karina's cheek. They held each others hands and Ranbir also called for some blankets.
However, the two did not doze off. Rather they were seen browsing through the pages of what looked like a number of scripts. They were seen animatedly discussing their parts and even mouthing a few dialogues.
Ranbir Kapoor was in Amsterdam to shoot for an advertisment, and Katrina Kaif had joined him there to spend some quality time.
