Jessica Simpson was all smiles as she walked the beach in Hawaii with fiance Eric Johnson on Wednesday! The romantic stroll came the day after Jess confirmed her second pregnancy on Twitter with a photo of her 7-month-old daughter Maxwell next to the words "BIG SIS" written in the sand.

Although Jessica did a pretty good job of hiding her baby bump in an oversized beach cover up, the frock did show off her still-slender legs, a result of the 50+ pounds she lost via a deal with Weight Watchers after giving birth to Maxwell in May.

Of course, now that the Fashion Star mentor is pregnant again, Weight Watchers announced that Jess will not be following her strict diet and workout plan over the next few months, although she will remain a spokesperson for the company. Looks like she's going to have to start all over again once the next bundle of joy arrives (per her doctor's permission)!

However, if you haven't gotten your fill of Jessica Simpson Weight Watchers ads -- don't worry! They're scheduled to continue airing through the winter.

How many kids do you think Jess will end up having?
