She told the publication: "Why don't you ask Cheryl? I don't know. It's got nothing to do with me.
"I've got Cheryl's number – we don't have to prove we're friends online.
"For me, it's not a publicity contest. I don't follow other celebrities to try and befriend them and gain public support.
She continued: "I’m a private person and if I want to speak to any of the girls, then I'll call them."
Well, maybe Sarah's tweet was the first step. Girls Aloud reunion anyone?
