She told America's Cosmopolitan magazine: "I just wanted to see what it was like to be with different people. I don't think a girl's a sl*t if she enjoys s*x.
"I could have a one-night stand, and I'm the kind of girl who looks over in the morning and is like, 'Do you really have to be here?' I don't need to cuddle and do all that stuff because I know what it is and I don't try to make it more."
Meanwhile, the stunning actress recently admitted her early onscreen kisses were "gross".

She said: "I was 12 years old and had to kiss this guy who was gross and never brushed his teeth.
"Then, at 14, I had to kiss a guy who was 32 or 33, and I was like, 'Ewww!' I didn't want to do it!"
However, the 'Sin City' beauty says her kissing experiences have since improved and her current boyfriend Cash Warren "is the best kisser in the world".
