X Factor Betting Odds - Dublin Mum Mary Byrne Favourite for Final Victory

50-year old Dubliner Mary Byrne has been installed by a bookmaker as their 5-1 betting favourite to win this year's X-Factor action following her stunning performance at the Croke Park auditions shown on last night's show.

The single mum from Ballyfermot in Dublin literally blew the judges away with her version of Dame Shirley Bassey's 'This Is My Life' and is already been heralded as Ireland's answer to Susan Boyle.

A spokesperson of Paddy Power commented: "X-Factor forums have been buzzing recently with rumors about Mary’s Croke Park performance and it seems they were absolutely right."

"We’ve taken over 200 bets on her to win this year’s X-Factor since last night's show was broadcast and already have been forced to cut her odds from 8-1 to 5-1. She seems to be the real deal and is definitely the one to beat", he added.
