Seven Sharp's Toni Street is distancing herself from an internet diet scam using her image to peddle pills.
Street said she was concerned people were starting to fall for bogus social media advertisements promoting Garcinia cambogia supplements.
The advertisements appear under the guise of a published article promising extra stones would vanish using the pills.
She used her high profile news show to slam the claims.
"You may have seen my face all over your Facebook feeds endorsing a miracle weight loss cure in some cosmopolitan article. In it I say that despite lecturing you all on the importance of diet and exercise I've been secretly popping diet pills and my lies have been exposed.
