Lovable Towie star James 'Arg' Argent plunged himself into freezing waters with members of a gym.
The reality TV personality joined staff at Fit4All fitness camp on the edge of body of water on a chilly February day.
Arg, who is regularly seen around Epping Forest rubbing shoulders with fellow celebrities, jumped in and swam a length.
The daring feat was undertaken for Haven House, which cares for children with life limiting illnesses and is Loughton based Fit4All's charity of the year.
Manager Nick Storan said: “We believe Haven House is a great cause, because they truly believe in the best possible life for every baby, child and young person who live in our local communities.”
“Whilst the ice plunge is testing and very cold, we are definitely going to be pushing the team to the limit through some much more demanding challenges this year, one of which will be a hike of Ben Nevis.
"We are really looking forward to raising thousands of pounds for Haven House throughout the year.”
