Reid and Shephard both got drenched after being nominated for the challenge by Good Morning Britain weather presenter Laura Tobin.
After having the icy water poured over them, Reid quickly nominated her co-presenter Sean Fletcher and This Morning's Ruth Langsford to take on the challenge next.
Langsford has agreed to take part in the task alongside her husband Eamonn Holmes, although he may be surprised when he finds out what his wife has signed him up for.
The Ice Bucket Challenge is a craze started in America that is raising money for the Amyotrophic Lateral Sclerosis (ALS) Association.
