Jennifer Hudson Weight Loss 2014: Singer Debuts Trim Bikini Body

Jennifer Hudson has debuted her bikini body on Instagram.

On Tuesday, the singer/actress took to social media during a vacation to Mexico, where she showed off her impressive weight loss in a yellow bikini.

"It would take Mexico to get me to play on the beach!" Hudson wrote on Instagram, along with a set of three photos. "I'm so not that girl! But I work hard, I deserve it right ! Plus, I earned it!"

In March 2014, Hudson parted ways with Weight Watchers after four years with the brand. While working with Weight Watchers, Hudson, who is known for her American Idol appearance and award-winning role in Dreamgirls, lost a reported 80 pounds, and while she may not be a part of their team at the moment, Hudson continues to look fit and trim.

In Nov. 2012, after two years on the Weight Watchers program, Hudson reached her goal weight, and in the years that followed, maintained that weight with a healthy diet and regular exercise.

Later that year, Hudson opened up about her weight loss.

"I'm at the weight I want to be," she told Redbook Magazine, via E! News. "But I hear all the time, 'Don't lose any more weight, you need to stop.' People are under the impression that I'm still losing but I'm not."

Also in the magazine, Hudson admitted that she wasn't quite used to her new, skinny frame.

"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,'" she said at the time.
