Kareena wasn't too happy with Salman's decision to cast Katrina in an item song. "Apparently, Salman's decision to rope in Katrina for a song in Bodyguard did not go down well with Kareena from the very beginning. Even on her birthday, Katrina dropped in to meet Salman only after Bebo had left the scene," a source told Mid Day.Bebo didn't want Kat to hog the limelight and demanded her song Teri Meri Prem Kahani to be hotter. She will be seen in a sultry avatar- dancing under the rain in a translucent sari. Though this track is hardly an item number, it has been designed to look like one, reportedly.Sneak peek: Bodyguard"When both Kareena and Katrina's songs will be released, there is definitely going to be comparison between the two. So Kareena wants to be prepared. The song Teri Meri Prem Kahani that has been shot over the past few days in three different locations is one of the sexiest songs Kareena has ever shot and she wanted it to be that way," added the source.Katrina has shot for item song Aayare Aaya Bodyguard... with Salman Khan for free. Producer Atul Agnihotri told the tabloid: "It is very gracious of her to have done this. She has always been very supportive of our work and is ready to contribute in whatever way possible. We have all known her for years now and she is part of our family. Even in my earlier film Hello, she had to do a guest appearance and she did it free of cost."Will Kareena be able to beat Katrina? Wait and watch!
