Piers Morgan has “shaken up” Good Morning Britain since joining the show as presenter, his co-host Susanna Reid has said.

Former tabloid editor Piers joined Susanna on the sofa in November 2015 and the duo have built up a reputation for their breezy on-screen relationship.

Appearing on ITV’s Loose Women, the former BBC Breakfast presenter revealed she had recently inadvertently admitted her love for Piers on Twitter after leaving her phone unattended.

“I went out of the studio on the pretext of going actually to interview my former co-presenter Bill Turnbull in the green room and I come back and apparently I’ve told the world ‘yes, it’s true, I love Piers Morgan’.”

“I’ve never seen so many tweets. ‘I love Piers Morgan I’ve finally admitted it’.”

She dubbed him a “cheeky monkey” over the prank.

Asked how she had adapted to life with Piers, Susanna said: “It’s been a fantastic year. Piers has been phenomenal he’s come in, he’s shaken the programme up.

“The audience absolutely love him, he’s got a very explosive personality.

“There is never a moment of silence because he is usually talking.

“He is explosive, he shakes people up, he wakes people up and I think I’m there just to provide a bit of calm, a little bit of balance.”

She said her Thursday shows when she presents with Ben Shephard were “therapeutic Thursdays”.

The host also spoke about GMB’s 1 Million Minutes campaign which encourages viewers of the ITV breakfast to pledge their time to volunteer for a lonely older person this Christmas.

Launching the campaign last week, the TV star was fitted with grey wigs and made up with prosthetic wrinkles and age spots to get an understanding of how it feels to be older.

“I still feel in my twenties and, of course, when I looked in the mirror made up as an 85-year-old I thought to myself ‘but I don’t feel any older’, and then I thought ‘but of course I won’t feel any older’.

“When I’m 85 I will still feel exactly the same as I do now so we mustn’t think of people as older people, they are just people, they are members of our family, they’re who we are going to be.”
