Salman Khan has asked his ex-girlfriend to appear for the one-off dance sequence in the remake of the hit Malayalam film.
"When both Kareena and Katrina's songs will be released, there is definitely going to be [a] comparison between the two," a source told Mid Day. "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."
The insider added that Kaif's late addition to the film had already created rifts on set.
"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 Katrina's birthday, she dropped in to meet Salman only after Bebo left the scene," the source claimed.
The item number starring both Khan and Kaif also features Khan's real life bodyguard Shera.
It is reportedly inspired by the famous opening credits of James Bond films such as Goldfinger and Octopussy.
