Kelly Osbourne says her friends think she is pregnant.
The 'Fashion Police' co-host, who is engaged to vegetarian chef Matthew Mosshart, claims that her best pals are convinced she is expecting her first child because of her new curves.
The 28-year-old star told People.com in New York: "I have no idea what's happening to me -- my boobs have grown very large and I don't know why. Everyone is like, 'You're pregnant, you're pregnant!' and I'm like, 'No! that's not happening!' "
Kelly insists she isn't upset about the rumours or her new curves, adding: "It's kind of fun, though. It's nice have them for once."
Kelly has lost more than 60 pounds over the last two years and credits Matthew for helping her to slim down but recently admitted she still struggles with her body image.
She said: "I'll never be the kind of person who thinks, 'I'm so hot.' I don't want to be. But I learnt to respect and love myself - something I didn't think I would ever be capable of. "
She added: "I'm happy with how I look now. As long as I'm healthy, do exercise and eat right, that's the main thing. I'm slim now, but I don't want to be anorexic. I love Matthew and we love to work out together - we motivate one another. I go on the treadmill every day for half an hour and do two hours of exercise if I have a special event."
