Bollywood's hottest couple Saif Ali Khan and Kareena Kapoor will soon reunite on-screen for Rensil D'Silva's 'Kurbaan'. The duo last shared screen space in Yash Raj Films' super-flop action flick, 'Tashan'.

According to reliable sources from the sets of 'Kurbaan', Saifareena is on a no-holds bared spree to outsmart critics who panned the lack of chemistry in their last outing. The source reveals that "Saifareena has canned the longest kiss in the history of Indian cinema for 'Kurbaan."

Recently, the first look trailer of 'Kurbaan' was unveiled, and it had showcased some steamy sequences featuring Saif and Kareena.

'Kurbaan', produced by Karan Johar, also stars Vivek Oberoi, Dia Mirza, Kirron Kher and Om Puri. The movie will be released on November 27, 2009.
