Jennifer Hudson Is Unrecognisable She Does A Duet With Her Former Self

The 30-year-old steps onstage in a size 0 figure, to sing with the older version of herself, when she was significantly heavier.

Looking incredibly svelte wearing a chocolate figure hugging bandage dress, she walks on stage singing The Four Tops hit  'I Believe in You and Me' to her image of old.

On the left, the former Jennifer is seen from her American Idol days, when she went on to become one the finalists in 2004, and then onto international stardom.

Age 23 at the time, the Academy Award-winner is barely recognisable in a pink strapless dress and hair in a head of ringlets.
