The new 'This Morning' presenter and 'Dancing On Ice' host Stephen Mulhern - who previously hosted companion show 'Britain's Got More Talent' and spin-off programme 'Britain's Got Talent: The Ultimate Magician' - are being eyed by producers to go on stand-by to cover for Ant Mc Partlin on the live shows if his wife Anne-Marie Corbett goes into labour.

The couple are due to welcome their first child into the world in June, so ITV bosses are worried Declan Donnelly could be left holding the fort alone if they don't draft up a contingency plan.

A source told The Sun on Sunday newspaper: “The timing is causing something of a headache for bosses.

“They are considering whether Dec would present alone if Anne-Marie went into labour or, if time allows, a guest presenter could step in.

"Cat and Stephen, who the lads have worked with in the past, are front-runners.”

Ant recently explained he and Dec - who has Isla, five, and 18-month-old Jack with his wife wife Ali Astall - are keen to spend more time with their families, which led to them "pausing" 'Saturday Night Takeaway' after 20 series.

He told Fault Magazine: "We do the show and then 'Britain’s Got Talent', but on a more personal level, part of the reason we’re pausing 'Takeaway' is we need a break ourselves, and we need to spend some time with our family. We’ve both got children that we need to spend time with for a little bit.

"We need time to think and, and time to step back and look at the bigger picture and just see where we are now. You know, like I say, 'We’re turning 49, and what do we want to do next? What’s the next phase of our career?' And we’ve got lots of ideas and lots of offers on the table, lots of options of things we can do.

"But it’s working on what we do next and where the next chapter begins. So that’s what we’re gonna do when 'Saturday Night Takeaway' is out of the way. We’ll sit down, take a bit of time, and reevaluate everything."
