Shrinking: Jennifer Hudson, who sang happy birthday to President Obama is reported to now be a size zero, after shedding 80lbs in two years
She has famously shed 80lbs and gone down a massive five dress sizes in recent years.
But now, the ever shrinking star Jennifer Hudson has shrunk down to a U.S. size zero, it has emerged.
On Friday's edition of U.S. talk show The View, presenter Joy Behar revealed that on a recent shopping trip, she bumped into the actress and overheard a salesperson tell the Dreamgirls star she was a size zero.
Slimline: Jennifer's weight loss was showed off to full effect in her slim black mini dress in Chicago earlier this week
Joy recalled she asked Jennifer how it felt to be the much coveted but controversially small size.
'I feel like they're talking to someone else,' she replied.
The Oscar winning star became a spokesman for Weight Watchers in April 2010, eight months after giving birth to her son David Jr.
The star showed off the results of her regime at a Chicago fundraiser earlier this week, singing 'Happy Birthday' to President Obama, where she appeared in a slim fitting black mini dress.

She initially dropped from a U.S. size 16 to a size four through diet and working out for regular workout sessions with personal trainer, Harley Pasternak.
She has expressed delight at her transformation, telling USA Today in January: 'Instead of saying I lost this or that, I [say I] feel like I gained 10 years of my youth back.
'I look 10 years younger. People say to me, 'You have Jennifer Hudson's face. Are you her little sister?'
