Jennifer Lawrence's breasts have a ''life of their own''.

The 22-year-old actress is amused by her ''bouncing'' assets and she thinks people are interested in her boobs because they are 100 percent real.

She told website Heatworld: ''I think people are fascinated with breasts that bounce. They are so used to seeing [fake ones].

''People are confused [that mine bounce]! My breasts have a life of their own.''

It was only earlier this month the 'Silver Linings Playbook' star revealed she is worried about her breasts being uneven.

Jennifer discovered she had unbalanced boobs when she had X-rays as part of her treatment for pneumonia and she was so concerned she asked her doctor for his professional opinion on her chest.

She previously said: ''I went to the doctor, I got a chest X-ray of my lungs and discovered that my breasts are uneven.

''I was like standing there with these doctors and they're like looking at my lungs and I just couldn't - it felt like an elephant in the room - and I was like, 'Are my breasts uneven?' And they were just kind of, like, stifled and uncomfortable, obviously. So I kept thinking, 'Well, I'm gonna dig myself out of this hole by bringing it up again.'

''So he was like, 'All right, our radiologist will get back to you about your lungs.' And I was like, 'And my breasts?' ''
