Prison Break star Wentworth Miller has insisted that he is unfazed by reports questioning his sexuality.

Although the actor has tried to set the record straight by confirming that he is straight, he added that he is happy for speculation about his personal life to continue because the reports are good publicity for the show.

"No, I'm not gay. I know these rumours are out there - I'm cool with the fact that they exist, I mean this is about fantasy," he told WENN.

"Certain people are going to have certain fantasies. If someone wants to imagine me with a woman, or a man or one of each, that's cool with me as long as you keep watching the show."
