Bollywood stars Katrina Kaif and Ranbir Kapoor are reportedly preparing a guest list for their housewarming party.

According to a report in Deccan Chronicle, the couple's home in Mumbai suburb is ready for the event.

"Professionally, they are doing well and they have successfully managed to sustain their relationship. Their housewarming has been pending for a very long time. It was Ranbir's idea to keep it private and low key and his parents Rishi and Neetu Kapoor have been supportive throughout. Before the housewarming, the Kapoor family will perform a small puja [prayer session]. The date of the party will be decided soon as the shooting dates of their film Jagga Jasoos have been finally locked in," a close source said.

It was previously reported that Kaif and Kapoor are living together, and she has been taking care of the 32-year-old Rockstar actor following his adenoid tonsil surgery.

"Ranbir is a very private person. He'd never talk about his personal life unless he wanted to," the insider added.

Kaif and Kapoor, who have starred together in the films Ajab Prem Ki Ghazab Kahani (2009; The Unique Story of a Strange Love) and Raajneeti (2010; a political thriller), have tried to keep their romantic relationship under wraps but photographs of the Bang Bang star holidaying with Kapoor on the island of Ibiza leaked online, sparking rumours that the two were dating.

Previously, during an interview with Times of India, the Hong Kong-born actress, who is a British national, talked about her affection towards Kapoor.

"I care a lot for him and feel protective about him. He has the capacity to be an extremely talented actor and a deeply evolved, highly intellectual and sensitive human being at the same time. He has the capacity and I can see the height of his potential," she said.
