Prince Andrew’s ex-wife Sarah Ferguson is set to guest edit This Morning and will be giving out relationship advice during her own agony aunt segment.
Fergie will join Alison Hammond and Dermot O’Leary for the special show, which she will also edit alongside boss Martin Frizell.
She said: ‘I have appeared on This Morning before, but this time I am coming back with a very different role.
‘I love live TV and am an enormous fan of the show, and the whole team is always lovely to deal with.’
She added: ‘I am thrilled to be guest editing the show, which will mean getting to explore some topics that I’m passionate about.’
Some of the other topics which she will discuss include importance of defibrillators, how best to rehome a dog, how to protect your skin, as well as an interview with Sir Cliff Richard.
This Morning’s editor Martin Frizell said of his new guest signing: ‘We are all delighted Sarah, Duchess of York wanted to come back here and I’m very happy for her to make some of my decisions on Monday.
‘She has a great understanding of the show and how television works and I feel viewers will be really interested in the running order she is putting together.’
There is no suggestion yet that Fergie – the ex-wife of Prince Andrew – will be a regular host but This Morning bosses have been screen testing several stars as they search for a new duo following the departures of Holly last month and Phillip Schofield in May.
While presenter Josie Gibson is starring on I’m A Celebrity, they have been auditioning live on television with the likes of Cat Deeley and Rylan Clark stepping in.
ITV bosses are likely to offer Cat, 48, the role after she impressed them when she hosted the show for three days last week with Rylan and then Craig Doyle.
Ben Shephard is also in the frame after he was due to join Holly as her permanent co-host in January when This Morning was going to have a relaunch in a bid to start a fresh following the Schofield scandal in which he admitted to having an affair with much younger male colleague.
Holly quit the show at the beginning of October after she learned of a plot to kidnap and murder her. She is currently taking time out from appearing on television.
Other names that have been mooted to replace her include Kate Garraway and Davina McCall.
ITV fans have called for Cat and Rylan to be the permanent hosts of This Morning after after only appearing on two episodes last week.
Viewers have called for the pair to be the permanent hosts of This Morning, while Cat is the bookies favourite to stay with 6-4 odds.
Taking to Twitter, now X, one person said: ‘Cat and Rylan are f****** LEGENDS! Peeing myself watching Spin to Win! PLEASE keep them’
Another penned: ‘Rylan and Cat Deeley should be the permanent hosts of This Morning’.
A third added: Oh come on @thismorning you know Cat and Ryland are a winning combination’
Fellow presenter Stephen Mulhern was in agreement and during his appearance on Tuesday’s show, he said: ‘By the way Cat, beautiful to see you on the sofa’.
