She explained: "We would literally be doing takes, and we were surrounded by real spring breakers. We were kind of thrown into this whole thing and just -- I've never seen anything like it. Literally, girls would be making out and their clothes would come off, and I was like, 'Oh God, the bottoms!' And then they'd come off. [I was thinking], I don't even know what I'm doing here."
Meanwhile, Selena previously admitted making the transition from Disney star to playing a college student gone wild in 'Spring Breakers', which features drugs, sex and violence, was "weird".
She said: "I am getting a little bit older, so I wanted to push myself and kind of get into a little bit more of an indie world. And it was a really great experience for me. And at the same time it has been, of course, a little awkward, but great.
"Honestly, it's been a weird transition. You never really know what's right or wrong and you can only do the best you can."
