The Dream Girl's got herself a dream body!

Jennifer Hudson showed of her svelte figure in a red-hot Atelier Versace gown at the 2011 Oscars.

After dropping five dress sizes and 80 pounds thanks to a rigorous diet and fitness regimen, as well as help from Weight Watchers, the singer claims she can't sleep at night because she is so excited for the clothes she will wear.

"It's like a brand-new me," the Oscar-winner told Oprah a few weeks before the Academy Awards. "Sometimes I don't even recognize myself."

And while we love that Hudson is proud of her new curves, our only criticism for our favorite "American Idol" contestant is that the dress is ill-fitted at the bust. The color, the cut and the accessories are all gorgeous choices, so she is still a best-dressed contender in our book.

Meanwhile, check out the 29-year-old's rare style misstep as she arrived at an airport.

And don't miss seeing Hudson on the red carpet if you didn't get a chance to before!
