Dublin star, Mary Byrne has made it through to the semi final of next weeks “X Factor”.

For the first time, Mary found herself in the bottom two last night as she was faced with a sing-off with controversial Wagner.

However there was little doubt in any one's mind that the judges would save Mary and send Wagner packing.

The Dubliner performed Shirley Bassey’s ‘This Is My Life’ in the sing off and was saved by all of the judging panel.

Speaking on The Xtra Factor after the final results were revealed, the 51 year old said: “I wasn’t even thinking about whether I was up against Wagner. I am fond of Wagner – I like him, he’s a nice guy.

“We were both hoping that we’d be saved, but as you know they can only save one person and I’m grateful they saved me, but I love Wagner.”

Despite having a stronger vocal talent than Vagner, the Tesco check out worker said she was still very nervous during the sing-off.

“My throat went completely dry,” she confessed. “Literally completely dry. And I got so shaky I went into the same verse twice but I just covered it up and I just tried to feel the song at the end. I was nervous all day – Shaking all day.”
