The presenter, 48, revealed she had been asked to do the ITV ice-skating competition a few times, but that she has always turned it down.
She explained that many years ago she hurt herself skating and has now been put off.
"I have been asked three times now and I say no every time," Hammond explained.
"I broke my ankle on ice so I have got a fear of ice."
Her co-host Dermot O'Leary also admitted he didn't fancy a spin around the rink any time soon.
Hammond asked if he would ever sign up for Dancing On Ice and he immediately replied: "No!"
He then joked that it wasn't him, but that his wife didn't want him to do it.
The pair were discussing the programme as they chatted to Carley Stenson, who is one of this year's contestants.
The actor and singer is one of the favourites in the competition but told the presenters that she and her pro partner Mark Hanretty will not be tackling the tricky headbanger move - because she promised her mum.
When O'Leary quizzed her about the challenging spin, Stenson said she wouldn't do it and joked that she was "forty years old and under the thumb".
"My mum's going to be traumatised that I am talking about this," she said.
"But yes, she basically was like, 'Oh Carley please don't do the headbanger. She made me say 'Honest to God' which is our family thing."
