BILLION DOLLAR CELEBRITY: Jessica Simpson Shows Off Her Super-Cute Kids And Spectacular Smile At Fashion Event

Jessica Simpson hit LA's Grove outdoor shopping mall to present the latest designs from her clothing collection, in conjunction with Nordstrom -- and we were left wondering what was cuter, her new pieces or her kids!

The working mom brought along daughter Maxwell Drew and son Ace Knute as hubby Eric Johnson watched from the sidelines in support of his awesome wife. Simpson's in the first celebrity clothing line in history to make $1 billion!!!! Nice work if you can get it!
