Jennifer Hudson is on a roll. The slim and trim singer put the "diva" in the VH1 Divas Celebrates Soul concert Sunday night, sporting a knit minidress and some killer thigh-high boots.
It's been more than a year now that Hudson has been strutting her fit figure on the red carpet -- she signed on as Weight Watcher's spokesperson in April 2010. And now, as overheard by Joy Behar, Hudson wears a size zero dress, quite an accomplishment for the "American Idol"-born talent.
