Pop star Britney Spears insists pregnancy leaves her feeling far from beautiful and glowing - despite posing naked with her bump on front of Harper's Bazaar. The TOXIC singer is expecting her second child with husband Kevin Federline in October (06) - a younger brother or sister for their 10-month-old son Sean Preston and Federline's children from his previous relationship, KORI and KALEB. While Spears was happy to strip off for the August (06) edition of the glossy magazine, she tells the publication ,"(during pregnancy) you don't feel the most beautiful all the time." Spears says the while she found expecting a baby "empowering", she was also "paranoid" during her first pregnancy. She adds, "This one, I was like, I've just got to wing it."
