For the first time since Jessica Simpson talked about her life as a new mom with PEOPLE, the Fashion Star mentor is expected to sit down for an interview. This time, with Katie Couric for the Sept. 10 premiere of her new syndicated daytime talk show, Katie.
Among the topics she’s expected to address: what life is like with daughter Maxwell Drew (born May 1); her efforts to lose the weight she gained during her pregnancy and her journey to get back in shape as part of the Weight Watchers family; and how she’s juggling being a mom and running a very successful fashion business.
“I think anybody who’s gone through a pregnancy, after they have the baby, it’s like, ‘I need to do something about this,’ ” Simpson, who’s engaged to Eric Johnson, told PEOPLE in May. “For me, I really want to do something that is a lifestyle, because in the past, I’ve been known to yo-yo diet.”
