Hollyoaks' Kirsty-Leigh Porter and singer Siva Kaneswaran are wanted for the next series of 'Celebrity SAS: Who Dares Wins'.
The 33-year-old soap star and The Wanted singer, also 33, are both said to have been in talks with bosses of the Channel 4 show about signing up for a brand-new season of the gruelling programme.
A source said: "Siva and Kirsty-Leigh are both sure-fire signings for the next instalment of SAS: Who Dares Wins.
"They have done their fitness assessments and are well on their way to signing on the dotted line for the show.
"Kirsty-Leigh became a mum for the first time last year and is looking to really challenge herself away from 'Hollyoaks'."
Pop star Gareth Gates - who shot to fame when he was the runner-up in the first series of the ITV talent show 'Pop Idol' in 2002 - is also on 'Celebrity SAS' bosses' shortlist.
The source added to The Sun newspaper's TV Biz column: "Gareth Gates is also on the line-up for the next series so it’s a real mix of characters."
A spokesperson for 'Celebrity SAS: Who Dares Wins' said: “In the best traditions of the SAS, this mission is confidential.
"However, full details will be released when the series broadcasts next year.
"In the meantime, tune into the current series of 'Celebrity SAS: Who Dares Wins', Sunday nights at 9pm on Channel 4."
Earlier this month, it was reported former Health Secretary Matt Hancock had been approached to appear on the show next year.
An insider told the publication at the time: “Matt impressed 'Celebrity SAS: Who Dares Wins' producers when he spoke to them and they want him to take part.
“He would be the biggest name to have signed up for the next series and it would be a real coup for the show.
“Matt knows there is a mixed perception of him in the public eye and he thinks going on the show would reveal a different side to himself.
“It is not unusual for MPs to take part in these kinds of shows and Matt thinks he could go far on SAS, despite it being the hardest of all the reality series on television.”
A spokesperson for the parliamentary representative for West Suffolk claimed he hadn’t “signed up for anything”.
They told the publication: "Matt gets a huge number of offers and is asked to appear on TV shows all the time but he has not signed up to anything."
