We can’t believe it’s been a whole 15 years since Girls Aloud were put together on Popstars: The Rivals. And now Cheryl has used this big day to share a touching tribute with her bandmates.

But despite describing Kimberly Walsh and Nicola Roberts as ‘gorgeous souls’, the mum-of-one chose to post a photo without Sarah Harding and Nadine Coyle.

Taking to Instagram with a sweet message for her pals, the 34-year-old wrote: “Crazy how time flies… 15 years ago today some of the best, craziest years of my life were just beginning”.

Sitting here drinking coffee with these two ☕️ and watching babies 15 years later !!! Crazy how time flies… 😱 15 years ago today some of the best, craziest years of my life were just beginning. I had no idea what a life journey I was starting out on. We had some of the most amazing times of our lives and made some incredible pop moments 💃🏻 to put the cherry 🍒 on top.. In the end I left with these two amazing, inspiring gorgeous souls and the best friends anyone could ever ask for. You blessed me 🙏🏻 and I will never be able to thank you enough for the support, love and loyalty you brought to our group. I am so proud of what we achieved together. Love you all @lilcola @kimberleywalshofficial @nadinecoyle @sarahnicoleharding Thank you 🙏🏻 ❤️ #Girlsaloud15

Reminiscing about her journey with the girls, Chezza continued: “I had no idea what a life journey I was starting out on. We had some of the most amazing times of our lives and made some incredible pop moments to put the cherry on top..”

She then said: “In the end I left with these two amazing, inspiring gorgeous souls and the best friends anyone could ever ask for.”

“You blessed me and I will never be able to thank you enough for the support, love and loyalty you brought to our group. I am so proud of what we achieved.”

And while Chezza DID tag Nadine and Sarah in the post – some of her 3.7million followers were not very happy with the photo.

“Childish not putting Nadine and Sarah in photo..after all its a very special day..”, one blasted.

Another questioned: “Why only two?!”, while a third agreed: “Shade but no shade”. And a fourth added: “Please take a pic of you all together”.

Nicola and Kimberley shared the exact same selfie of the three-piece from their ‘girls day out’ – while Sarah and Nadine have yet to post anything online. Hmmm…

It’s no secret that the band haven’t always seen eye-to-eye and after they took a ‘brief’ hiatus in 2009 (which sadly turned into a permanent hiatus), Nadine claimed the ladies made the decision to split without telling her.

Cheryl – who welcomed baby Bear with boyfriend Liam Payne back in March – later fumed that her former pal was ‘full of sh*t’, and hasn’t had much to do with her since.
