Getty Images for Jessica Simpson

They're both so gorgeous -- and goofy!

On Saturday Jessica and Ashlee Simpson stopped by the Perimeter Mall in Atlanta, Georgia to promote Jess' clothing line, and the ladies posed for several photos before greeting fans at Dillards. Jess also tweeted a sweet selfie of the girls and wrote, "Simpson Sisters take Atlanta!"

Jessica has been all over the place lately to promote her fashion line, but even though she's jetting back and forth between Los Angeles and New York City to make appearances, she's made plenty of time to hit the gym and keep her figure looking fab. The other day X17 photographer snapped the 34-year-old starlet wearing a tiny black romper, and she's clearly very proud of her tight and toned bod.

The Weight Watchers spokeswoman, who recently appeared on The Today Show, revealed that the harsh words about her body actually helped motivate her "to rise above and stand up for all the women out there that do have trouble losing the weight." Good for her!

And of course, Ash's new hubby Evan Ross just HAD to make an appearance too:
