The model-turned-actor, who appeared in a pair of revealing yellow trunks in the first film, is to now go one step further, claims The Times of India.
Director Tarun Manukhani commented: "This time you get to see the entire butt and frontal view too."
The next instalment, which reunites Abraham with Abhishek Bachchan and Kirron Kher, shifts location from the original Miami setting to London.
"Everybody I am meeting these days wants to know when the sequel is going to release. I am under immense pressure from people who loved Dostana," said the filmmaker.
The follow-up to one of the top-grossing films of 2008 is expected to begin shooting in April next year, once Abraham completes Desi Boyz.
