Earlier on the show, Madeley also paid tribute to legendary wildlife presenter and comedian Bill Oddie, whose representative David Foster announced on Monday that he had died at the age of 85.
"It is with deep sadness that I announce the passing of Bill Oddie, the country's best-loved birder," said Foster.
"Bill was a multi-talented celebrity - wildlife presenter, broadcaster, comedian, writer, songwriter, musician and conservationist. Yet it was never fame that he valued," said Foster.
Madeley reflected on his past professional experiences interviewing the late conservationist during the morning broadcast.
"He was spikey, you really had to get your boxing gloves out when you interviewed him. You couldn't say the wrong thing," said Madeley.
The Monday episode of Good Morning Britain also featured meteorologist Chris Page making his debut appearance on the national broadcast, temporarily filling in for regular weather presenters Laura Tobin and Alex Beresford.
"We've got a new weather guy today! If you are in the Anglia region, you'll know him - he's been doing it for years there.
But he's got up very, very early and he's come all the way down from Norwich. Here's Chris with the weather," said Madeley.
