Believe it or not but Bollywood hunk Salman Khan is keeping a close tab on the Box Office collections of Shah Rukh Khan’s latest outing ‘Don 2.’ Apparently, Salman has been checking on the Box Office collections of Farhan Akhtar’s film for the past couple of days.

Talking to a daily, a source said, “Salman was keeping an account of the collections of ‘Don 2’ ever since it hit the theatres on December 23. Distributors were calling him up every hour to keep him updated on the latest collections.”

“Salman was even taking down notes. After he had evaluated the weekend collections of the film, Salman was heard telling his friends how it was important not to waste money on film promotions,” the source said. Interestingly, Salman did not give away his real feeling towards the raging success of ‘Don 2’ as the source added, “He kept a poker straight face. We couldn’t guess how he felt.”
