Nadine Coyle begged Sarah Harding not to do Celebrity Big Brother, it's been revealed.
Chatting this week, Nadine told The Sun newspaper that she was "petrified" after learning Sarah was heading into the house.
She recalled: "She called to tell me she was doing it and my immediate thing was, 'Don't. Absolutely not. Why? Stop this immediately. Retract, retract.
"Don't do it. Just don't do it. We'll go on a holiday. I'm going to Spain, come'."
But Nadine conceded: "She wanted to do it. And if she's got it in her mind she's going to do something, she's going to go and do it."
Earlier this week it was claimed that Nadine and Sarah's fellow bandmate Cheryl did tune in to watch Sarah on Celebrity Big Brother.
Sarah's former housemate Paul Danan said Cheryl's boyfriend Liam Payne revealed to him she had been watching.
However, he says that the Girls Aloud star apparently found it tough going seeing her former bandmate in the house.
“Cheryl watched a little bit, he said. She didn't watch loads. She didn't watch it all. I did ask and she watched a little bit," Paul explained. “But I suppose she didn't want to see Sarah in the way Sarah was, because it was heart breaking.
“To see someone very vulnerable and not in the best of shape and Big Brother can do that to someone - make them even worse.
"Should she have done the show? Yeah, she won it.”
And Paul added: “Liam so wanted me to win. And I'm sure Cheryl did too."
Celebrity Big Brother will return for a brand new series in January on Channel 5.
