Kelly Osbourne has posted a picture of herself on her Twitter webpage showing a burned armpit, which she says was caused by using body spray.
Kelly Osbourne has been burned from using deodorant.
The presenter - who is currently competing on US TV show 'Dancing With The Stars' - posted photographs on her Twitter webpage of her painful-looking red armpits and has blamed a body spray she used.
She wrote on her page on the microblogging site: "Never ever use impulse body spray from the UK i sprayed it on myself and now have really bad burns all over my body, gentle on skin my a*s!
"That's just my armpit the one on my tummy is much worst! (sic)"
The burns were so bad her costume for the dance contest had to be altered to hide them.
She added: "They just had to send my dress for tonight back to fix so it covers my burns."
A spokesperson for Unilever, who manufacture Impulse in America, said they are "looking into" Kelly's burns.
They said: "We are looking into the incident that Kelly Osbourne reported, and appreciate her feedback and input."
