Brookside star Claire Sweeney has been offered a deal with ITV to host her own primetime show.
She will front 12 episodes of Challenge of a Lifetime, a spin off from Don't Try This at Home, the Saturday evening challenge programme.
London Weekend Television, the producers of the programme, said Sweeney had been granted "special leave" from soap Brookside, in which she plays single-mother Lindsey Corkhill.
Sweeney said she was really looking forward to becoming a presenter, adding she had enjoyed her first taste of the challenges ahead.
She said: "I whet my appetite yesterday by hanging off the edge of a cliff and paragliding from the top of the Alps.
"I wasn't sure what my phobias were and I'm still not, but I know it's definitely not heights."
The star impressed programme makers during Celebrity Big Brother, when she was locked up in a house with five other celebrities as part of Comic Relief.
In the show Sweeney will be seen flying to exotic locations around the world, preparing to take the place of anyone who refuses to do the challenge.
Bob Massie, head of entertainment at LWT, said: "Everyone loves Claire. She proved during Celebrity Big Brother that she's got bags of personality and loads of charisma which makes her the perfect choice to present this ITV primetime show."
Sweeney added that she had no plans to quit Brookside.
She said: "They [Brookside] have given me time out to do this.
"Lyndsey will always remain in Brookside. It is being left open for me to go back. I would always like to go back and do some stuff with the other Corkhills."
Brookside creator and producer Phil Redmond said: "I am absolutely delighted that Claire has found another avenue to display the range of talents we could never fully explore in Brookside."
He added: "Everyone here wishes her well and is fully supportive."
Challenge of a Lifetime has been described by LWT as a completely new show, based around one element from Don't Try This At Home
