Kareena Kapoor Khan has started shooting in Kalimpong hills for Sujoy Ghosh's crime thriller, which is based on the book Devotion of Suspect X.

Here, she is seen pouting with co-star Jaideep Ahalwat, as they hold the clapper board of their untitled film that marks her OTT debut. “Getting one of the finest performers to do the toughest performance…the pout! So much to learn from each other….” she tweeted with the picture. Kareena, who arrived in the hills on May 10 with her younger son Jeh, is likely to stay here for around a fortnight.
