Jessica Simpson and Eric Johnson rode a tandem bike along the boardwalk in Venice Beach, CA, yesterday. Eric sported his usual neon shades while Jessica wore a pair of sturdy cowboy boots and short shorts for their afternoon by the water. The pop star and Jessica Simpson Collection designer was back in sunny LA after traveling to Denver to sing for military families, and then stopping in Chicago with her fiancé, earlier this month. Now that the couple are home, they've set a date and are planning their upcoming nuptials. Jessica and Eric have kept mum on most of the details about the big day, but Jessica did hint that she'll seek out a wedding gown that shows off her famous assets. Jessica Simpson also downplayed wedding fitness regimen reports, joking that she'd be just as happy getting married in sweatpants.
