Jennifer Hudson took to Instagram to show off her weight loss in a hot bikini shot from an undisclosed Mexican beach. Jennifer Hudson's weight loss has been the subject of surgery rumors, but  that is not the case. Hudson credits Weight Watchers, who she was affiliated with for years, until a recent amicable split.

Jennifer Hudson has been working hard to lose weight. Jennifer lost about 80-pounds and hit Instagram on June 18 to show off her hot slim body in a skimpy yellow bikini.

Hudson recently posted some super-sexy bikini pictures on Instagram saying "It would take Mexico to get me to play on the beach ! I'm so not that girl ! But I work hard , I deserve it right ! Plus, I earned it !"

In November, the American Idol star told Redbook she hit the weight she wanted to be saying "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."

The Dreamgirls actress is a former Weight Watchers spokesperson. Hudson Weight Watcher parted ways in March after "four years of a successful and rewarding partnership."

Hudson just released a new music video for her hit single, "Walk It Out."
