Actor Katrina Kaif, 27, has trashed reports that suggest she is a big fan of international rapper Pitbull. “It’s not true. I am not going for any of his concerts. I don’t even know who he is,” Kat said. Pitbull is set to visit India on Dec 2 for a three-city tour. Buzz is that he has also been approached to sing in Dhoom 3.
