The Wanted singer, 27, and the former 'Hollyoaks' star, 31, have been roped into joining the line-up for the forthcoming series as backups in case another celebrity pulls out.

The duo have been hitting the Austrian slopes with the likes of 'The Only Way is Essex's James 'Arg' Argent and Rebecca Adlington for basic training in case they're forced to stand in at the last minute due to unexpected injuries on the snow.

And Gemma - who was known for playing Carmel Valentine in the Channel 4 soap until 2014 - is no doubt hoping she'll get the chance to prove herself following her fail on 'Splash!'

Tom, on the other hand, has never competed on a reality TV show like this before, apart from when he successfully sailed through to the semi-finals on 'Celebrity Masterchef' in 2015.

Meanwhile, 'The Jump', which will be hosted again by Davina McCall, will return to screens across the nation later this month on Channel 4, as a string of celebrities try their hand at skeleton, bobsleigh, giant slalom and speed skating.

Girls Aloud's Sarah Harding, former 'EastEnders' star Sid Owen, sporting legend Linford Christie and ex-Westlife hunk Brian McFadden have all been confirmed for the new series.
