Lots of people have not recognized Jennifer Hudson post diet .
Ms Hudson has stated that her old friends almost did not recognize her after dramatic weight loss .
Last month, the greatly slimmed down celebrity became the new face of Weight Watchers, after shedding the equivalent of four dress sizes after the birth of her second child in the summer of 2009.
She started the Weight Watchers diet because she was getting frustrated with not losing weight consistently any other way.
Ms Hudson is satisfied with results of the diet and feels much healthier.
