Simpson and Hudson tout the benefits of Weight Watchers in the latest "Expect Amazing" ad, posted on YouTube today and debuting on TV Thursday. "I naturally became a healthier me," says Hudson, who went from a size 16 to a size 6 in 2010, when she was Weight Watchers' celebrity spokesperson. Simpson, who took on that role in May and lost more than 50 pounds, says "I amazed myself."
With another baby on the way, Simpson is no longer following the Weight Watchers program. On Christmas Day, the singer turned fashion designer revealed that she's expecting her second child. She's since showed off her burgeoning baby bump on Twitter.
