The former Girls Aloud star made the promise after she was asked by Brandi Glanville whether she and Chad Johnson have had sex during their time in the house.

During a tense exchange, Brandi asked: "So did you guys have sex yet?"

To which Sarah - who was seen kissing the American hunk over the weekend, before crawling into his bed - insisted: "No it's not like that."

But Brandi refused to let the issue die and he continued to probe the 35-year-old star.

He asked: "No make-outs?"

At that point, Sarah asked Brandi to "stop" with his questions, before she added: "I mean it's on camera. People were talking about it, if it happened it happened."

The singer subsequently explained: "No, I'm not going to do anything like that in the house, that was just a different.

"I don't know, I've just got to maintain some decorum while I'm in the house and respect other people."

Meanwhile, Sarah previously admitted she is "sick of being judged".

The singer revealed 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.

Of her time in the 'Celebrity Big Brother' house, she previously explained: "This is for me like getting a second chance to show people who I've grown into and I'm kind of a bit sick of being judged on the past because we all grow up at some point in our lives and you learn by your mistakes and your regrets.

"I want to make the most of this experience. It's not every day you get another opportunity to sort of make the most of your life."
