The 28-year-old today tweeted a message of support to Cher, 18, and Rebecca, following the release of their first solo material this year.
She wrote: 'Feels like I've blinked and we're back in November. It's been a crazy year. So proud of what my girls have achieved. @CherLloyd and @RebeccaFMusic are doing so well!!'
Cheryl also posted a link to Ferguson's video for debut single Nothing's Real But Love along with the word 'Wow.'
Cole, who is currently working on her third solo album, missed out on performing a duet with Gary Barlow at a Children In Need charity event in Manchester last week because she was ill.
