Filmmaker Karan Johar will start shooting the sequel to 'Dostana', a light-hearted tale about three friends, this summer with actors Abhishek Bachchan and John Abraham once again in the lead.

''Dostana 2' starts filming this summer. The final cast will be announced (by the) end of the month...of course flagbearers AB (Abhishek) and John lead the way,' Karan, who produced the first movie in 2008, posted on micro-blogging site Twitter.

The filmmaker, whose last release was Shah Rukh Khan-starrer 'My Name Is Khan', says preparations are in full swing for the forthcoming movies under his banner Dharma Productions.

Karan is completing the last shooting schedule of his yet untitled film with Kajol, Kareena Kapoor and Arjun Rampal. The upcoming movie is an adaptation of Chris Columbus' 1998 comedy-drama 'Stepmom'.

Also, Saturday will be the last shooting day for 'I Hate Love Stories', starring Imran Khan and Sonam Kapoor.

'Sonam Kapoor's last shooting day today for 'I Hate Love Stories'...one song with Imran Khan left and its a film wrap...summer release,' he posted.
