India, Nov. 20 -- Come December, and Canadian singer-rapper AP Dhillon will be here for his eight-city pan-India tour. And we have learnt that the shows are set to be star-studded affairs, with actors Ranveer Singh and Sanjay Dutt expected to join him onstage as surprise guests. "Singers Karan Aujla, Shreya Ghoshal, and Anuv Jain, as well as cricketer Hardik Pandya, are also touted to join him," a source tells us. In Dubai earlier this year, the 32-year-old was joined onstage by singer Yo Yo Honey Singh and American rapper Swae Lee. During his India tour last year, actor Malaika Arora and singer Jazzy B surprised fans at the concert. The upcoming tour, which will kick off in Ahmedabad on December 5, will see Dhillon being joined by long-time collaborator Shinda Kahlon. The musician's setlist will span hits including his latest releases Afsos, Without Me and Thodi Si Daaru, as well as previous hits such as Brown Munde and Excuses. Rs.100 from every ticket sale as well as merchandise proceeds will go towards relief efforts for those affected by the Punjab floods....
