04 March 2010Kelly Osbourne has denied rumours that she achieved her new, slimmer appearance through cosmetic surgery, stating that she will not be considering undergoing surgery until she's older. In her weekly column for Closer magazine, the 25-year-old reality TV star expressed her frustration with people saying she had undergone plastic surgery to drop to an American size six."I'm so angry there are rumours going around that I've had fillers in my lips, or liposuction on my legs," Kelly wrote. "Someone even said I've had a gastric bypass! I have 100 per cent not had any of that. I've lost weight from my face, and that's why it looks different." Kelly said she might consider cosmetic surgery in the future, but that she hasn't so far. Kelly told readers: "I can say with confidence that the only time I've been in a plastic surgeon's office was with my mum." Sharon Osbourne has always been open about her cosmetic surgery, having undergone a face lift, liposuction, tummy tuck and breast augmentation in recent years. Sharon revealed that she was "short, fat and ugly" when she was younger, which led her to develop her famous personality. While Kelly has battled her own issues without cosmetic surgery so far, it remains to be seen whether she chooses to follow in her mother's footsteps in the future.
