"Shahid is being repeatedly offered to be a part of the world tour with Ranbir. But due to his 'Mausam' release and Sajid Khan's film shoot he has declined the offer," said Shahid's spokesperson.
When contacted, Mohammed Morani of Cineyug, which is organising Ranbir's world tour, said: "Yes, it's true that we have approached Shahid Kapoor to be a part of the world tour, but we are still awaiting his reply. Most probably he will say yes. The tour will take place June-July 2011."
Shahid's known for his hit numbers like 'Dil vich lagya ve' ('Chup Chup Ke'), 'Mauja hi mauja' ('Jab We Met'), and 'Dhan Te Naan' ('Kaminey').
Shahid's success has made him a heartthrob and he enjoys a huge fan following. Many feel that if the two Kapoors team up for the stage show, it can create a sensation, said an insider.
Right now Shahid is shooting for his father Pankaj Kapoor's directorial debut 'Mausam'.
World tours, of course, are all about stars. For instance, during Amitabh Bachchan's 'Unforgettable' concert, stars like Akshay Kumar, Preity Zinta and Madhuri Dixit had joined him at different places besides his son Abhishek and daughter-in-law Aishwarya.
Earlier, Shah Rukh had teamed up with Saif Ali Khan, Rani Mukerji, Arjun Rampal, Preity Zinta and Priyanka Chopra for his 'Temptation' world tour.
For Ranbir's tour, Priyanka Chopra and Katrina Kaif are said to be on board.
