{blackbabes} Jennifer Hudson looks great - even without her sparkler

Jennifer Hudson is an emblem of the efficacy of dieting and exercise, but when she showed up to dedicate a Weight Watchers storefront in New York, the buzz was about what she wasn't wearing: her engagement ring.

The singer/actress was "minus a few ounces," cracked Yahoo about Hudson's appearance on Monday night. "Think Hudson simply forgot to put on her bling?"

Oscar winner Hudson, 31, who's been engaged to WWE's David Otunga for four years and has a 3-year-old son with him, is the proud possessor of a huge Neil Lane diamond ring.

But it was nowhere in evidence when she posed and sat for interviews at the event to celebrate Weight Watchers' 50th anniversary. The new storefront was dedicated to company founder Jean Nidetch.

Hudson was svelte in a gold skirt and fitted black top, and could not have looked healthier. She's an ideal spokeswoman for Weight Watchers, having lost 80 pounds while on a WW diet and a good exercise regimen.

She and Otunga lately have not been seen together at publicity events such as this. She was alone at this year's Academy Awards and Vanity Fair's after-party. When Otunga attended the Hollywood premiere of his movie The Call, he went with their son, David Jr.

Significant? We'll see.
