Jessica Simpson says her daughter made her presence known early on. “We were just about to [go] all-day drinking,” the singer and Fashion Star mentor recalls to Elle , which features Jessica Simpson nude on the cover of its new issue. “We were off to ride our bikes, hang out. But I felt this overwhelming guilt. Why would I feel guilt at the idea of going out and having cocktails with friends?” With an inkling that something was a little off, the 31-year-old Simpson took a home pregnancy test – and discovered she was expecting with fiance Eric Johnson. Instantly, her life changed. “I’m a free-spirited girl, but giving up my scotch? My Macallan 18? That was hard for me!” she says.
