Jennifer Hudson is still adjusting to her slimmer figure.

The 31-year-old 'Think Like A Man' singer - who lost more than 80 pounds through a deal with Weight Watchers over the past two and a half years - has revealed she still isn't used to her new body and people's reaction to her now that she is trim and toned.

The mother-of-one told the upcoming issue of Weight Watchers magazine, which will be released on Tuesday (12.02.13) that she had an identity crisis after slimming down initially because she ''got used to being plus-sized, whereas now it's like, 'Ok, who am I?' I keep thinking that I probably need an extra-large or a large, and the stylist is like, 'No, you need a medium or a small.' I'm still discovering myself, as well as how I'm perceived.''

The 'Dream Girls' star also revealed she has had no problem keeping the weight off because she has fallen in love with exercise and it makes her feel powerful.

She said: ''Jogging makes me feel powerful and free! I like changing myself. I liked who I was before I lost weight, and I like who I am now.''

Jennifer will continue to be the main spokesperson for the lifestyle and diet plan while it's other celebrity endorser Jessica Simpson is pregnant.

The 'With You' singer - who was reportedly paid $4 million to become the brand's ambassador - is expected to resume following the program after the birth of her second child.
