Jennifer Hudson, who underwent a dramatic weight loss since her campaign with Weight Watchers now wears a size 0.

Joy Behar, co-host of "The View," told a story on an Aug. 5 episode about running into skinny Jennifer Hudson, shopping for a size 0, in a store.

"I heard the sales girl say to her, 'You're a size 0' and I said to Jennifer, 'How does that feel?' and she said 'I feel like they're talking to somebody else,'" Behar said on The View.

After losing 80 pounds since becoming a Weight Watchers spokeswoman in April 2010, Jennifer Hudson dropped from a size 16 to a size four, and now according to Behar, a size 0.

"Being skinny, it's a job. It's not easy," Hudson said in a public comment for Weight Watchers. "I feel this responsibility to the world now - people are watching, so I have to keep going in the right direction in terms of my weight loss."
