The Hills star Audrina Patridge has dismissed reports she has undergone plastic surgery to achieve slimmer facial features, insisting she's "just losing baby fat."

The 23 year old is preparing to launch her own reality show, which will follow Patridge in her personal and professional life.

But the brunette has laughed off claims she's had various medical procedures done to enhance her looks as she pitches the show to TV networks.

She tells news show Extra, "People think I've got my nose done, my chin done. I just laugh at it. I'm just losing my baby fat - everyone grows up and changes."
