In an interview with TV Times, Charlotte spilled: “I’m feeling the pressure because Piers Morgan told me not to return to the Good Morning Britain studio if Dan Walker wins because he has a rivalry with BBC Breakfast.
“The last thing I need is Piers coming along and yelling at me from the sidelines, but maybe he could put off Dan with some insults!” she said.
Meanwhile, BBC newsreader Sophie Raworth insisted that competitors were taking the rowing challenge with good humour.
The 49-year-old said: “My team are a competitive lot, but it’s all in good spirit.
The controversial journalist explained that the 37-year-old had been celebrating the night before, exclaiming: “Beresford was at the final party for Dancing On Ice, despite coming fifth. And then pulled a sickie.
“I was like, ‘Really mate? You’re celebrating coming fifth so much you can’t come to work?’”
Good Morning Britain continues tomorrow on ITV at 6am.
The BBC versus ITV boat race will air on BBC One during Sport Relief 2018 on March 23.
The full interview can be seen in the latest issue of TV Times, which is out now.
