Pop star Britney Spears' revealing new Harper's Bazaar cover has been a long time coming - the pop star was desperate to pose nude while she was pregnant with baby Sean Preston. The newly-brunette singer has bared all for the provocative new August cover shot, proudly showing off the bulging belly that holds her second child. Her representative explains, "This was an idea she had when she was pregnant with SEAN, but we never really got to it. "Unfortunately, with Britney's first pregnancy, it was a little bit difficult for her to even walk around because everyone was so on top of 'Britney Spears is pregnant!' "There was just too much hype." The rep claims the cover shoot was scheduled before the TOXIC singer announced her pregnancy and Spears is thrilled with the results. She adds, "The photos are beautiful. The photos are art. They're classic, iconic portraits of a very happy woman."
