She added: "You learn by your mistakes and regrets".
Sarah replied: "I washed my hair today, I put on my orange lippy I'm just not doing it again.You know, I'm just chilling". It's not for me to say.
Sarah was prompted to reflect on her experience in the band after performing a rendition of the Girls Aloud hit The Promise in a CBB talent contest with X Factor finalist with Amelia Lily. "Nothing lasts forever. We went through so much, even if had fallen out, I'm sure it wouldn't be a major deal in the future". I mean, we were like sisters, so of course it would never be plain sailing the whole time. Being around girls all the time, it's hard sometimes.
It starts with the pair discussing the heights of the girls with Sarah remarking how she used to feel like a giant next to Cheryl.More news: Frank Clark held out of Seahawks practice Friday
Will we get any more Girls Aloud news as the show goes on or will Sarah be able to stick to her guns and keep her lips sealed about the band's inner-most secrets?
Sarah last appeared on "Xtra Factor" November 2014, when she came out in support of Cheryl and her one remaining act, Lauren Platt, suggesting that was the last time they spoke.
The 35-year-old singer insists she doesn't have a "thick skin" and is grateful for having a "second chance" to show people who she is after feeling lost following Girls Aloud's split. I don't like bringing up... talking about the other girls.
"When that all ended, I was like, 'Where do I go from here?'"
