Cheryl is reportedly holding back a possible Girls Aloud reunion.
The former X Factor judge, who recently welcomed her first child, is said to consider the idea "cringe".
Girls Aloud were formed on Popstars The Rivals back in 2002 and were one of the first - and even to this date, very few - success stories from such shows.
They split up in 2013 but this autumn will celebrate their 15th anniversary together.
While some of the group have expressed hope of a possible reunion, Cheryl is apparently against the idea.
A source told Now magazine: "Cheryl told Kimberley she's not even considering reforming Girls Aloud. She thinks it's all a bit The Big Reunion cringe."
Cheryl and Kimberley's former bandmate Sarah Harding recently said she'd love the group to reform for their anniversary.
Sarah told OK! magazine: "I don't think it'll happen any time soon, but I'd love the chance to do something again. A lot of our fans would love us to comeback so we'll have to wait and see what happens."
She continued: "We've not seen each other properly for years but Nadine and I still message each other. I don't live near any of them so its hard to make time to see each other.
"Cheryl, Kimberley and Nicola are really close but Nadine and I are much more independent.
"We might have gone our separate ways but we were like sisters for years, so I'll always care about them."
Meanwhile, reflecting on the past 15 years with the group, Sarah said this month: "I don't know where the time has gone. I get really nostalgic when I think about being in Girls Aloud.
"I found a CD of our Radio One Live Lounge performances the other day and it was so nice to listen back and hear us all bantering with each other. I really miss performing with the girls on stage."
