Stars including Taylor Swift, Susanna Reid and Jennifer Lopez have taken on the ice bucket challenge, a task which sees them throw a bucket of freezing cold water over themselves in the name of charity.
The challenge, which began taking place after a campaign to raise awareness for the disease ALS, sees participants nominate at least three others, who should then take part and post their efforts on social media.

So far, plenty of famous faces have got involved, including Taylor, who is now calling on her celeb pals Ed Sheeran, Emma Stone and Selena Gomez to hop onboard.
Like many participants, Taylor has also donated cash to the cause and a number of charities are benefiting from the craze, including the ALS Association and Macmillan in the UK.
Susanna took things one step further by completing her ice bucket challenge live on ‘Good Morning Britain’.
Of course, after receiving his nomination from Ryan Seacrest, David Beckham was never going to refuse...
The craze has taken over social media websites, much like the #nomakeupselfie trend, which raised over £8 million for Cancer Research UK.
One person who perhaps needs to cheer up a little is Lady Gaga as her vid is well… rather bizarre.
