Pregnant Britney Spears has vowed to get in shape again after the birth of her second child in October (06). The EVERYTIME singer, 24, has been criticised by her fans and the media after appearing to become disinterested in her physical appearance since she starting dating her now-husband Kevin Federline in April 2004. Spears tells the August (06) edition of Harper's Bazaar, "It was weird for me at first because of who I am. Wherever you go, they expect you to look a certain way. I'm not supposed to be this big huge pregnant superstar. "After this baby. I'm going to get really intense with it (working out)."
