Alex recently went on maternity leave from the evening magazine show to have her third child.
Posting on Instagram last week, she wrote: “And just like that it’s time to say goodbye to the show temporarily and get ready to welcome our little girl.
“Thank you to everyone who sent their best wishes tonight.
“You’ll know that I’m prone to a good cry on the show at the best of times but seeing those messages at the end, especially from mum and dad and Charlie really set me off.
“Thanks to our viewers for helping keep me sane during this last year and a half and for the warm welcome every night.
“I’ll miss being on that sofa at 7 and of course, the brilliant team who work so hard behind the scenes.”
