Abraham shares screen time with Khan in Baabul and there have been news reports about Khan making snide remarks about his co-star and a squabble during the making of the film.
"All I can do is brush it off with a smile. I really don't have time for all this," Abraham was quoted as saying in a leading daily.
So what about rumours of a squabble between them during Baabul and Rockstars tour? He says, "Well, I had no issues with him any time during the concerts. I didn't know what was happening until I returned to Mumbai and read reports in the papers about our hostility. And we hardly shot together for the film."
"As far as I'm concerned I'm very comfortable with everyone around me. I don't like to work under any kind of stress and avoid it as much as possible. I am comfortable in my space, and that's what matters to me," he adds.
There were no comments from Khan.
John, 33, started acting three years ago. Since then he has often been voted as one of the sexiest stars in movie polls.
He has starred in several blockbuster movies since he struck fame in the 2004 hit Dhoom. Apart from Baabul, he is also currently starring in Kabul Express, where he plays a television journalist covering the war against the Taliban in Afghanistan.
Both films will hit theaters later this month.
