None of the acts that featured in week two of the series managed to impress the firm enough to displace Attraction as the 3/1 favourites to win this year's show.
Jordan O'Keefe is the highest placed entrant from Saturday night's acts as the 7/1 second favourite, with sandwich making duo, Richard and Adam, quoted at 12/1 to sing their way to success.
Impressionist Francine Lewis is currently chalked up at 14/1 to be the winning act and introduce Her Majesty to 'Amy Childs' and 'Stacey Solomon' at the Royal Variety Performance.
Despite MC Boy getting the BGT audience on their feet he's an outsider at 100/1 to go and win the show.
Jessica Bridge of Ladbrokes said: "After week two of BGT auditions Attraction are looking safe at the top of the market. At this stage only Jordan O'Keefe looks to be their biggest threat."
She added: "I Need You Tonight could be the next Gangnam Style, but if Simon Cowell has anything to do with it MC Boy will remain a rank outsider for BGT glory."
