Britain's Got Talent judge Amanda Holden is taking Holly Willoughby's seat on the This Morning sofa while she goes on maternity leave.
She will join co-host Phillip Schofield on the show for four days a week from September with husband-and-wife team Eamonn Holmes and Ruth Langsford continuing to appear on Fridays.
Holden said: "I'm over the Moon to get the chance to present one of my favourite shows on TV and I'm thrilled to be keeping Holly's seat on the sofa warm when she goes off."
Willoughby, whose third child is due in October, has said she wants to keep working as long as possible. ITV said Christine Bleakley will also present some of the shows missed by Willoughby while she is on leave.
