"Katrina was apprehensive about how Salman would behave on their first film together after the break-up. He has always been unpredictable. But he's been looking after her, making sure she's comfortable. He has been protective towards Katrina," says a source, who was in Dublin.
Far from being bitter, Khan is said to have taken his friendship with Kaif to another level. "It's obvious they are in a happy place," says the source.
Thanks to Khan, the actress is said to have gathered an interest in checking out the Irish capital's nightlife.
"They are having a ball together, and they deserve it. It's been a stressful time for both. For Salman, on the health front, and for her, because she's been overworked. We are shooting nights here in Dublin, and that's tough on Katrina, but great for Salman. He is a 'night person'," says the source.
"When did we become enemies? Salman is and will be there for me," said Kaif over the phone from Dublin.
