A little birdie told us that how Bebo was mighty upset when she got to know about the hot item number that Katrina is performing with ex-beau Salman Khan in the film ‘Bodyguard’. Bebo, who happens to be the leading lady of the film, demanded a hotter number.

Speaking to a daily, a source said, “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."

The song features Kareena in a hot avatar. The song is also the theme song of the film. And though it`s hardly an item number, there are portions of the song, which have now been designed to look like one.

The two actresses have been pitted against each other before, but professional rivalry has never been this out in the open.

Added another source, “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.”

Interestingly, when asked to confirm the news, both Kareena and Katrina denied the story.
