Holly Willoughby jumped into the pool at the London Aquatics Centre fully clothed on Tuesday evening at the end of The Games live show.
The This Morning presenter, 41, threw caution to the wind and dove in alongside fellow presenter Freddie Flintoff after the celebs had competed in the Olympic pool.
Holly doused her chic navy blue blazer and matching Karen Millen shorts in chlorine as she embraced her fun side.
