This Morning host Holly Willoughby has vowed to get her own back on The Chase presenter Bradley Walsh after he pranked her live on-air on Monday.

Walsh phoned in as 'Roger Smythe', a former army officer and head teacher who is homeschooling his 16-year-old son James and finding the experience very difficult. 

James, played by Walsh's son Barney, told Willoughby, co-host Phillip Schofield and guest Vanessa Feltz that his father is too strict and is giving him detention in his own room.

Later in the show, Willoughby reassured viewers that they were contacting the family and "giving them a bit more advice".

"You've been done again!"

Co-presenter Schofield couldn't keep his laughter in any longer.

"It wasn't genuine," he said. "You've been done again! It's Bradley Walsh."

"You're kiddng me!" wailed Willoughby. "I hate you all!" 

Watch the fun above.
