Jessica Simpson has confirmed she’s having a baby girl and says her impending bundle of joy is expected to weigh in at a healthy 10 pounds. The reality-star-turned-fashion mogul further reveals in Elle’s April issue that she and fiancé Eric Johnson have already picked out a “nontraditional” name. “We’re sure,” Simpson said of the choice without revealing the name. “We’re embroidering it on things.” She says the name is “nothing shocking and nothing you’ll have to add to the dictionary . . . When people hear it, they’ll know . . . why.” And it won’t be “Chicken of the Sea” after her most famous line from “Newlyweds.”

According to Elle, Simpson’s moved beyond her days as a reality TV ditz to a “billion-dollar-per-year business” with her Jessica Simpson Collection, as well as star of NBC’s “Fashion Star.” The mag says TV exec Ben Silverman is developing a sitcom for her. She also reveals that she initially found it difficult to wrap her head around abstaining from top-shelf whiskey while pregnant. “Givin’ up my Scotch? My Macallan 18? That was hard for me! . . . Though now . . . being pregnant. You crave other things. A big thing of water sounds great!”
