Taking to social media, the This Morning veteran is keeping fans updated on how she's enjoying her time off, and that includes quality time with her children.

'I think you sort of get – the children are a little bit older, so I've got a little bit more time for myself. And I'm always one of those people that if you feel happy and healthy that's all that matters', she said.
