TV star isn't close pals with the Girls Aloud singer
‘It’s really personal and I wouldn’t class her as my best friend by any means,’ she explains.
Holly, 27, who is due to give birth in May, plans to continue hosting the ITV2 show after she becomes a mum.
‘It wil be busy but you just have to make these things work,’ she tells OK!
‘And it’s so much fun I wouldn’t want to miss out on it for the world. I’m lucky with the job I do as I can bring my baby into work and not many people can do that.’
