Amanda Holden broke her leg in two places in an accident on an inflatable assault course during her half-term family holiday.
The Britain's Got Talent judge underwent an operation and has had a metal plate fitted in her leg.
Holden’s injury came as she was playing in the sea with her family.
She told the Sun: “I suffered a nasty accident while playing in the sea with the family during our half-term holiday and subsequently broke my leg in two places.
"I had an operation on Friday and a metal plate was fitted."
Despite the surgery, a spokesman for the star said it is "business as usual" for the star and she will return to host her Heart Breakfast show on Monday October 28.
Holden is married to record producer Chris Hughes and the couple has two daughters - Alexa, 13, and seven-year-old Hollie.
Last week Hollie lent her mum a hand at work, helping her interview Hollywood star Angelina Jolie.
The mother-daughter duo quizzed Jolie and her Maleficent co-star Elle Fanning shortly before the film's London premiere.
