Teaming up with brother Adam, 20, the pop duo from Woodside Road, Northgate, hoped to follow in the footsteps of last year's sibling finalists Same Difference.

But Christian Sarah – who had already been 'asked to leave' her church band - was told to sling her hook by telly's Mr Nasty Simon Cowell.

Calling themselves Agasimba – meaning 'Land of Gold' in Zimbabwean – the duo crooned the slushy ballad 'Time of My Life'.

But the Dirty Dancing classic didn't go down well with the judges, who said that Adam looked 'constipated' before giving the pair four nos.

Sarah said: "There is a lot that goes into the show behind the scenes.

"You have three auditions before you even get to sing in front of the judges.

"They were not as scary as they seem on TV. "When we went into the audition room we were so nervous to be in front of Simon Cowell. But in the end I thought Louis was the meanest judge.

"It just shows that looks can be deceiving. He was quite harsh and a bit rude and had a mean expression on his face the whole time.

"Truthfully – the judges told my brother he looked constipated, and they gave him advice to get some dance lessons to try and loosen him up.

"Simon also said that it wasn't an appropriate song for a brother and sister to sing, but it was just a song.

"Dannii said the same and said it didn't look right with us. "They didn't really say that much to me, apart from that I went off key a few times."

She added: "Unfortunately we didn't get a single yes from the judges, which was quite upsetting.

"Because we are Christian Simon Cowell said he was expecting a Christian song from us, and we had one prepared but as soon as we started to sing it he told us to stop because he didn't recognise it, which is why we hadn't sang it in the first place.

"I think I probably valued what Cheryl said the most, she was very understanding because she had been through a similar situation before with Pop Rivals."

Adam was filmed going about his daily duties as a motorcycle courier at City Sprint's Gatwick Service Centre, which will be aired together with the duo's audition in the coming weeks.

He said: "We were quite calm up until the audition at the Emirates Stadium.

"When you're standing on stage with Simon Cowell and all the other judges in front of you it does get a little bit intimidating."

Sarah, who used to be part of a band at New Hope Church in Bewbush before being told she could be more use elsewhere in the church, still sings in the bath and the shower, and has vowed to give the X-Factor one last shot.

She said: "I will be entering again next year on my own."
