Susanna Reid 'didn't want anyone to hear' her sweary reaction to Piers Morgan joining GMB

“Trying to work out how much weight I’ve put on and hair I’ve lost,” the father-of-four remarked.

“There’s at least a stone difference for both of us,” added Susanna, who turns 50 next month, while introducing the clip.

“Congratulations to the whole @gmb team for getting through the last five years…” she joked online today after her co-host tweeted a picture of the pair on set today.

“Happy 5th Anniversary @susannareid100 – you lucky devil!” Piers wrote in view of his 7.6 million followers.
