The New York Post's Peter Lauria reports that a rift is developing between Martha Stewart and the newly crowned co-CEO of her company, Wenda Harris Millard. According to multiple sources close to either Stewart or Millard, the pair isn't seeing eye-to-eye on a number of operational issues and has not yet "gotten on the same page" since Millard was named co-CEO of Martha Stewart Living Omnimedia in June. In an interview with The Post, Millard conceded that there was "healthy debate" within the company, but she denied any row between her and Stewart. "I've worked with Martha in some capacity for more than four years, and I deeply admire and respect her," Millard said. "We've made enormous strides together and I'm looking forward to more great things to come." The Post posits that if the friction between the women gets so bad that Millard begins looking to leave, one open position that she is certainly qualified for would be the top job at Microsoft's Internet business. Microsoft said it would conduct a search for someone to lead its online business -- including its search and advertising operations -- after Kevin Johnson left in July. It has yet to announce a new hire. Before joining Martha Stewart, Millard was the well-regarded chief sales officer for Yahoo!, which she left last year.
