Kelly Osbourne laughs off pregnancy rumours

London: TV presenter Kelly Osbourne has denied reports that she is pregnant with her first child.

Speculations about the 28-year-old's pregnancy began last week when Osbourne said her breasts were swelling up.

She posted a photograph of herself on her Instagram page, and captioned it: "My t**s are getting so big therefore I am the fiercest of them all."

However, Osbourne, who is engaged to chef Matthew Mosshart, has also earlier said that she isn't prepared for motherhood just yet.

"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!'," she said.
