She has beenlinked with three actors - Hurman S. Baweja, Shahid Kapur and Hollywood star Gerard Butler of '300' fame - all within a span of oneyear, but the mystery behind Bollywood's svelte actress Priyanka Chopra's actual love interestcontinues.

The rumour mills started working overtimeafter Butler, whom she met at the launch of the Atlantis hotel in Dubai lastyear, was quoted as saying in a leading daily: "I don't mind gettingmarried to an Indian girl. Too bad Priyanka already has a boyfriend".

Now, who that boyfriend is, remains to beknown.

Though rumours of a romantic liaisonbetween Shahid and Priyanka have been in the grapevine lately after their jointappearance at filmmaker Tarun Mansukhani's birthday party in Mumbai last week,neither has confirmed the development.

The two will be seen together in VishalBharadwaj's 'Kaminay'.

"Priyanka has always maintained silenceon her private affairs. Till date, she has never gone public about her personallife and she will continue to do so," a source close to the actress toldus.

Even when news of her affair with her 'LoveStory 2050' co-star Hurman was doing the rounds, Priyanka remained politicallycorrect. While Hurman was very vocal about their relationship as well as theirbreak-up, the supermodel-turned-actress chose not to speak about it.

Now, the news about the friendship betweenPriyanka and Butler, who is currently in Jaipur, is raising eyebrows.

But the source clarifies: "He (Butler)is in Jaipur with four of his friends as part of an India tour.

"He came to Jaipur and knew thatPriyanka was shooting and staying at Shiv Vilas for her film 'What's Your Rashee?'.So he came to the sets to meet her as they are good friends and to see what anIndian film shoot looks like. He also met all important people on the sets andwas also introduced to Ashutosh (Gowariker) and Hurman. Priyanka and him arejust friends only," the source said.

Butler, who played the role of King Spartan in '300', has also been linkedto former 'Friends' star Jennifer Aniston, which he has denied.
