Jessica Simpson and Eric Johnson Kissing in Mexico

Jessica Simpson and Eric Johnson headed south of the border earlier this week on a romantic private getaway to Mexico. On Wednesday the engaged couple were spotted lounging around the pool at their resort when Jessica playfully planted an upside-down kiss on Eric. Today the pair boarded a private jet headed back to LA, and Jessica tweeted a photo of herself boarding the plane in a tropical dress along with the message, "Sad to leave Cabo, but not the mosquitoes." The short getaway allowed Jessica a few days to relax before tackling a hectic month ahead. Fall Fashion Week is just around the corner for the designer and her ever expanding line of clothing, bags, and shoes, and she's continuing work on her new reality show, Fashion Star.
