Speaking in her column for British OK! column this week, Walsh discussed 27-year-old Cheryl's X Factor news after it was confirmed yesterday that she will be replaced by Nicole Scherzinger on the judging panel of the US talent competition.
Kimberley, 29, said: 'You have probably been reading a lot of stories in the papers about Cheryl being in hiding and down in the dumps, but I would just like fans to know that I've been speaking to her and she's fine.
'Cheryl's had a lot to deal with over the years, both personally and health-wise, so all the current media stories aren't going to be a huge deal for her.
'She's got Will.i.am too, he's a good friend and he's totally got her back, which is great.'
The Like U Like singer added that one good thing to come out of this is that she's got her friend living close by her again.
She said: 'I'm very protective of Cheryl and I'm a firm believer in what is meant to be will be and, from a selfish point of view, I'm glad I can pop round again for a cup of tea!'
