Hollywood waistlines appear to be thinning, with some cases causing alarm. Though the super skinny celebrities hardly admit that they suffer from any eating disorders, it is almost unbelievable that they could lose so many pounds in a matter of months.

Timeless beauty, Demi Moore, has sparked a discussion about her extreme obsession with her body, and the recent weight loss, which seems to be killing her famous curves.

Moore attended Variety's 3rd Annual Power of Women luncheon in Beverly Hills, Calif., Friday, dressed in a white sleeveless dress, which stuck to her skinny figure, raising concern among her fans and nutritionists.

The 48-year-old actress and mother of three, recently confessed her fixation with maintaining a perfect figure. I had an extreme obsession with my body. I made it a measure of my own value. I tried to dominate it, which I did, and I changed it multiple times over, Moore said. But it never lasted and ultimately it didn't bring me anything but temporary happiness. Does being thin resolve anything? No. The irony is that when I abandoned that desire to dominate my body, it actually became the body that I always wanted.

She may or may not have abandoned the idea of perfect body, but going by the appearance Mrs. Ashton Kutcher seems to be spending way too much time in her gym.

Other Hollywood celebrities who hit the news with their skinny figures are singer LeAnn Rimes, reality star Nicole Snooki Polizzi, actress singer Jennifer Hudson, actress Sofia Vergera.
