In the photos, the former Weight Watchers spokesperson showcases her new slim figure at an undisclosed beach in Mexico following her 80-pound weight loss. Hudson and the weight loss company parted ways in March after "four years of a successful and rewarding partnership."

"I hear all the time, 'Don't lose any more weight, you need to stop,'" the Dreamgirls actress told Redbook. "People are under the impression that I'm still losing but I'm not."
