Kelly Osbourne has denied speculation that she is expecting a baby.

The celebrity recently announced her engagement to boyfriend Matthew Mosshart and this has helped to fuel pregnancy rumours.

The new suggestion started after Osbourne recently posted a picture of herself online alongside a comment that said her "tits" have become bigger.

Speaking to People, however, the Brit denied that the increase in her breast size was due to pregnancy. She said:

"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!'. It's kind of fun, though. It's nice to have them for once."
