The singer confirmed her second pregnancy on Christmas via photo. And although she won't stick to her diet plan now that she's in the family way again, she will continue to appear in ads for the brand.

"There have been no changes to our business agreement with Jessica," a rep for Weight Watchers told ABCNews.com. "Jessica's successful weight loss prior to becoming pregnant will be featured in Weight Watchers' new 'Expect Amazing' advertising campaign, including a spot with her sharing the happy news."

According to the same spokesperson, Simpson "will not be following the program during the pregnancy while her weight and well-being are monitored by her obstetrician, as is recommended for any woman during pregnancy. After she gives birth, Jessica and her doctor will decide when she may resume following the Weight Watchers program."

Phew. Now, a collective sigh of relief.
