Sian Welby is set to co-host the ITV show
The 37-year-old TV presenter will co-host the ITV show alongside Dermot O’Leary next week, and Sian is already being tipped as a "star of the future".
A source told MailOnline: "Sian has many years of presenting experience under her belt, she is very much ear marked as being a star of the future."
Sian has already made a number of cameo appearances on the show, and she'll now be given even more responsibility.
The source added: "She has done really well already on 'This Morning' so the bosses thought it was time to give her the reins to the whole show rather than just segments."
Sian - who previously hosted the news on Channel 5 - is expected to bring something "fresh" to the long-running TV show.
The insider said: "Viewers love a new, fresh face on the show so everyone involved in it is really excited."
Meanwhile, in October, Holly Willoughby announced that she was quitting as the co-host of 'This Morning' after 14 years on the show.
The 42-year-old star said in a statement at the time: "I have let ITV know today that after 14 years, I will not be returning to 'This Morning'.
"To everyone who has ever worked on the show over the years, thank you so much. This is such a difficult goodbye, you are incredible and I forever will be proud of what we’ve done together. Thank you to everyone at ITV for being supportive. To every guest who has sat on our sofa, thank you.
"Most of all, thank you to the wonderful viewers. You’ve been so loyal, so supportive and the best company every day."
