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 IANS 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".
