Jessica Simpson looked holiday-season ready leaving the Ritz Carlton Hotel in Manhattan to head over and film her new Macy's Christmas ad today. The singer is getting into the dress-making business and totally looked the part, strutting her stuff and steaming up the city as usual. While we'll be waiting for it to get a little cooler out before we see this commercial, there will be a lot more of red hot Jess in her favorite short shorts as she tours around performing at fairs this August.
