Jennifer Lawrence unable to control breasts

But she's still proud of her pair - insisting it's a novelty in Hollywood to have boobs that still jiggle.
 Jennifer Lawrence claims her breasts are out of control - and once doubled in size overnight, reported British daily The Sun on Tuesday.

The actress's ample rack recently helped her win the title Sexiest Actress Alive in an online poll.

But she complains she struggles to keep the celebrated pair contained.

The Silver Linings Playbook star even had to ditch a dress she planned to wear to the Golden Globe Awards, after her knockers grew too big.

Jennifer, 23, told Heatworld at the Baftas last week: "My breasts have a life of their own.

"I’m wearing a dress for the Baftas that I was supposed to wear for those awards, but, randomly, my breasts doubled in size the night before, so I couldn’t wear it."

It's not Jen's only complaint about her boobs - after revealing during a recent TV interview that they're actually uneven.

She told talk show host Jimmy Kimmel: "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?’"

But she's still proud of her pair - insisting it's a novelty in Hollywood to have boobs that still jiggle.

She told Heatworld: "I think people are fascinated with breasts that bounce. They are so used to seeing (fake ones)

"People are confused (that mine bounce)!"
