Never let it be said that Lauren Conrad can't handle a little bit of helmet hair. The up-and-coming fashion designer and former reality star shared a photo of herself all strapped into a go-kart during a recent romantic excursion with her husband, William Tell, from Monday night.We're glad to report that she donned appropriate protective gear, as well as what appears to be a yellow skull-cap underneath. (Safety — and flyaways — first!) From the looks of things, this shot was snapped right before the couple took off.
