To celebrate her birthday and to begin her search for the perfect outfit she'll wear at the upcoming CMA Awards, the sassy and sultry Jo Dee Messina hits the Big Apple for a well-deserved shopping spree. With two Country Music Association Award nominations and an appearance on the awards Show, Messina is also going to have a busy CMA Week! Nothing, however, could stop her from saying "yes" to CBS This Morning Entertainment Editor Mark McEwen when he asked her to be their CMA correspondent for the CBS wake-up show. "I was blown away that they'd ask," Messina says. "I am a huge fan of Mark McEwen, and it was so cool getting to do the show with him this spring. I was thrilled at the invitation ... and am honored to be part of their team for that morning." In addition to doing some arrival interviews and one-on-one interviews with the winners after the show, Messina will set up her piece and perform live on CBS This Morning September 23rd.
