Salman Khan is very upset with Katrina Kaif over the issue and has collected some solid proof against her to prove his point. Sources say that Salman Khan is in possession of Katrina Kaif’s phone bills, which clearly point out that Katrina Kaif has been in touch with Salman’s foe John Abraham. Salman is known to keep tabs on his girlfriends. Reveals a source close to the actor, "Salmanbhai got hold of Kat's mobile bill and saw many calls and SMSes made and received between John and her."

Katrina Kaif has come to know of Salman Khan’s method of inquiring about her phone calls and is running scared of him. Though the buzz doing the rounds in the industry is that Katrina is no longer with Salman Khan, but she would not like to antagonize him at any cost.Katrina knows that Sallubhai is a powerful figure in bollywood and can make or break her career even at this stage. Though Katrina does not have any of the movies opposite Salman Khan, but he can still influence the decision of other filmmakers.

As a source close to Salman says, ‘everyone in the industry is talking about this changed equation between Kat and John. There will surely be repercussions to this new development’.

It is believed that when the rumours of Katrina and Ranbir first appeared, Salman called up the Saawariya boy and asked him if he and Kat had something going on. Kapoor assured him that he was serious about Deepika and that he wouldn't dream of cosying up to Salman's girl. Luckily for him, Khan chose to believe him.

While Katrina and John remained unavailable for comment, a friend of Abraham rubbishes these rumours, "There is nothing going on between him and Katrina. Someone is just targeting him. The truth will come out soon."

It may be recalled that John Abraham and Katrina Kaif have been paired in Yashraj Films’ upcoming film ‘New York’ and the film is almost complete and ready for release. Cynics say that this might be just another way of promoting their movies by Yash Raj or some other interested party of the film.

Whatever may be the truth about Katrina and John Abraham’s romantic liaisons… but considering John’s past history with his co-stars (remember Vidya during Salaam-e-Ishq)…..Bipasha Basu must be on guard.
