The 44-year-old presenter is "very excited" about her new co-host - who she is fronting the show with three days a week - and has warned the audience to "expect the unexpected" when he is on air.

She said: "I'm very excited, he's lovely. Expect the unexpected - he'll be making all sorts of headlines.

"He's a force of energy, a mini tornado whirling through the studio. Although I think he'd take exception to be describing him as mini...

"He does genuinely seem very excited to be joining the team."

Her current co-host, Kate Garraway - who will continue fronting the show on Fridays - added: "He's good fun isn't he? A mischief maker."

Susanna is a big admirer of Piers' blunt interviewing style as she thinks he gets a lot more out of his guests than other presenters do.

She told OK! magazine: "He's not afraid to take risks. Sometimes the audience will say, 'Wow I can't believe you said that.' He takes celebrities by the scruff of the neck and shakes something different out of them."
