The actress has gone on an impulsive two-week holiday to US

Priyanka Chopra has taken off for an impromptu two-week holiday. The actress left for the US immediately after attending the film awards event in Toronto.

"She needs to destress, " says a source. "PC has been going through a lot of tension."

Barely had she finished with 7 Khoon Maaf that she plunged into Agneepath, where she plays the role of a sex worker's daughter trying to leave her past behind.

Then there is Burfee where she needed intense preparation for her part as a mentally challenged girl."

The source continues, "Then came Kunal Kohli's film where she not only had to play several characters going through various phases, she also had to face the camera with Shahid Kapoor with whom her relationship is under constant scrutiny."

All this has apparently, taken a toll on her. She has decided to take some time off to be with people whom she can be herself with.

Adds the source, "She has gone through professional and personal setbacks. Anjaana Anjaani and 7 Khoon Maaf under-performed at the box-office. Personally too, she has been going through a tough phase."

The actress will spend her holiday connecting with people who have nothing to do with her profession and stardom. Says the source, "She's visiting friends and and family in the US.This is her way of staying rooted to reality.

Outwardly, Priyanka seems a very strong self-dependent girl but, only she knows how much of an effort it has been to shoot with Shahid after they've called off their relationship.

The one friend during this stressful period has been Shah Rukh Khan. But people have started making uncomfortable insinuations which have hurt her. She wanted to get away from it all."
