The ice bucket challenge has been accepted by celebrities such as David Beckham, James Franco and Colleen Rooney and was started in aid of ALS (Amyotrphic lateral sclerosis) but has now started to benefit various charities.
Now, Katie Hopkins has agreed to take on the ice bucket challenge, letting her followers know via Twitter.

Katie responded to the YouTube video which sees the thirty-year-old British rapper being soaked by a bucket of icy water after challenges from Tori Kelly and wife Millie Macintosh.
The rapper says: "I choose to nominate Theo Walcott, Robbie Williams and last but not least, Katie Hopkins" before adding, "be a good sport darling".
Katie replied to Professor Green's tweeted video, saying "@professorgreen you naughty pants, you are on."
She added, "Except tough birds don't wear girlie hats. Friday is the day", poking fun at Professor Green's cap which protected his head from the cold water.
We bet Professor Green can't wait to see Katie getting drenched on Friday, revenge is a dish best served cold.
