Hudson has been a face behind the weight-loss company for four years.
Jennifer Hudson has parted ways with Weight Watches after being a face behind the brand for four years.
The 32-year-old singer tweeted about her leave early Friday saying, "Sometimes you have to step back and let your work speak for you, and when that doesn't work you walk away knowing you did your best...It's been fun and a pleasure good luck to you all. @WeightWatchers."
Hudson's rep later confirmed the split between the singer and the company. During her commitment to Weight Watchers, Hudson lost 80 pounds and dropped from a size 16 to a 6.
"My experience with Weight Watchers has truly been life changing," Hudson said in a statement Friday. "I am grateful for what I have learned throughout the process and will always take it with me. I have chosen to step away from my role as ambassador and I am excited for the year to come, with many new projects and lots of new music."
