Katrina Kaif, who was last spotted at Arjun Kapoor's birthday bash on June 26, made news as the actress opted to leave the party early that night. This lead to a speculation that she had a fight with boyfriend Ranbir Kapoor at the party. Apparently, it was Arjun and not Ranbir, who escorted the actress to the car as well.

However, based on sources close to the actress, the real reason was 'Dhoom 3', as the actress had to rest well, to perform the heavy-duty acrobatics as part of a song shoot for the film, the next morning.

It is also reported that the shoot is taking a toll on the actress' health and she is now under the weather. Doctors have asked her to take complete bed rest until she recuperates.
