Sarah Harding has spilled on a rift between herself and her former Girls Aloud bandmates.
They parted ways after more than a decade together in 2013 and Sarah has admitted she's not spoken to "one" of them "for forever".
In tonight's episode of Celebrity Big Brother, Derek and Sarah are in the garden, talking about Girls Aloud.
Sarah says; “It’s so hard to catch up with any of them, really. Everyone has got their own thing going on.
"Three of them have got families now... I haven’t seen or heard from one of them for forever. I don’t know where she’s gone.”
Sarah adds that she has recently facetimed Nadine.
In a previous episode of CBB, Sarah reflected on her time in Girls Aloud while chatting to Amelia Lily who supported the group on their final tour.
Amelia said, “If I could relive anything in my career, it would be your tour. I had the best time.”
Sam asked Sarah what her top moment was when Girls Aloud were at the height of their fame and she revealed, “Probably the Brit Awards. But then when we met the Queen as well at the Royal Variety. I’ve got one more, at Wembley Stadium supporting Jay Z and Coldplay.”
Sarah also discussed her 'feud' with Cheryl on the show as well.
Asked if they fell out, Sarah said: "Everyone asks that. It's just that we’re so busy with our own stuff... It’s not for me to say, honestly.
"I don’t like talking about the other girls”, she replied when fellow housemate Jemma Lucy asked if they are still friends. "We were like sisters, so it was never going to be plain sailing the whole time.
"I've been around girls all the time, it's difficult sometimes.
"Nothing's forever. We went through a lot together, nothing lasts forever, we went through so much.
"Even if we had fallen out I'm sure it wouldn't be a major deal in the future."
