Jennifer Hudson has pulled a disappearing act on us. She was so svelte in her Tangerine Orange Versace dress at the Oscars, she nearly vanished when she turned to the side.

Okay, slight over-exaggeration, but seriously, she looks great!

J-Hud told Hollyscoop her big weight loss secret has been to cut out carbs entirely.

“I just made sure I stuck to my Weight Watchers…I also took the extra mile to delete the carbs,” Jennifer told Hollyscoop on the red carpet.

She added, “I didn't eat any carbs until today. I made sure when I felt the need to eat something crunchy I ate nuts instead and stayed away from the carbs.”

A skinny bod wasn’t the only thing this Oscar winner was sporting, she had a huge smile on her face and told reporters “I feel good, what else can I say?”

J-Hud also dished on the new season of American Idol and playing Aretha Franklin. Check out our exclusive interview below…
