After her break-up with long-time beau John Abraham, Bipasha Basu is now being linked to her "Singularity" co-star Josh Hartnett.

But the dusky beauty is unperturbed and believes link-up rumours are a part of her profession."Link-up rumours don't bother me any more. At the end of the day, whatever two people have, it is for them to know. The world speculates and let them do that," Biphasha told over phone from Murmansk, Russia.

"All these things are a part of our business and both Josh and I understand that. This discussion of link-ups will happen for ever. What is important is that the two people who are being spoken about should know what the truth is and what is not," added the actress who was recently seen in "Dum Maaro Dum".

Bipasha, now 32, started her career as a ramp model and then dazzled on the silver screen with her debut with "Ajnabee" in 2001. She also featured in hits like "Race", "No Entry", "Phir Hera Pheri", "Omkara" and "Dhoom 2".

After her break-up with John with whom she worked in "Jism", "Madhoshi", and "Dhan Dhana Dhan Goal", her growing friendship with Josh was talked about as a potential romance, but the actress maintains she only shares a working relationship with the American actor.

"It's been great working with Josh because he is immensely talented and he is always very kicked about the work he does. He is a very nice person to work with. We got along very well and we intent to keep in touch. I can easily say that because of this film ('Singularity') , I met an interesting person," she explained.

"Singularity", a period film, is being helmed by Oscar-nominated filmmaker Roland Joffe. The film, which kicked off production in Queensland, later moved to India and was shot at places like Gwalior and Orchha in Madhya Pradesh.

After completing the shoot in Orchha, where the temperature was 40 degrees Celsius, Bipasha immediately flew down to Murmansk, where the temperature is -35 degrees Celsius, to shoot for Abbas-Mastan's "Players".

The film also stars Abhishek Bachchan, Bobby Deol, Sonam Kapoor, Neil Nitin Mukesh, Omi Vaidya and Sikander Kher.

Asked how she was coping with this sudden change of weather, the actress said: "Coming to this schedule is an experience. There is nothing much that you can do here because there is just snow... it's very barren, very few people, and communication is also tough since most people only speak Russian here. Hence a lot of sign language and broad smiles work."

"The team I'm working with now is very special. I get along with everyone on the set very well. So the excitement to work is there," she added.

So is she a winter lover or a summer fan?

"I'm a crazy person, my preferences change with every year. I love the sun because I love the pool and the beach. But winter is fine too, since I was born in January in Delhi, I take less to the cold," she answered.
