Bradley Cooper has revealed there is one aspect of fame he cannot stand - photo shoots.
The actor has become a household name following roles in The Hangover, The A-Team and Limitless, but still can't get used to standing in front of the cameras.
"The only thing I hate are photo shoots, I cannot stand them," he said.
While Bradley isn't a big fan of the paparazzi, he has got used to them, unless other people enter the picture.
"The paps I got used to very quickly, you have to buy that into the process by which you're going to live your life. That only changes when people come into your life," he continued.
"My father just passed away, so now my mother lives with me, so now my mother in turn has to deal with the paparazzi, which bothers me because she didn't ask for it."
The 36-year-old recalled: "For the most part, they're OK, but at the airport the other day, we were waiting for a cab with all this luggage and we were ambushed. I just felt that thing in the back of my head go, 'Ah, I want to hit this guy because he's not stopping' which is the worst thing you can do because that's all they want.
"Show any sign of aggression and they think they've got a live one and then they're going to be all over it, so it's such a process of constant restraint," he added.
