As the live show kicks off right now on ITV, the Hungarian group are tipped to win, but comic Jack Carroll is not too far behind.
The shadow dance troupe remain the red-hot favourites to be crowned as this year's winners, however in the past 48 hours Attraction have drifted slightly to 2/7 in the betting.
Jack's sitting pretty in second position at 5/1, whilst Richard and Adam appear to be struggling to drum up support with the general public as only 15 bets have been placed on the duo in the last seven days.
Joseph Hall is strongly fancied by the firm to waltz his way into this final as the wildcard act, and should he do so it's a 66/1 chance the wildcard winner causes an upset to the odds by winning BGT.
Jessica Bridge of Ladbrokes said: "The stats are against Attraction as only one favourite has gone on to win BGT since the show started, but we're fairly confident Attraction will buck the trend on Saturday night."
She added: "Their only real competition is Jack, the public love him and in reality the final could be a lot tighter than what the odds suggest."
Britain's Got Talent 2013 final airs at 7:30PM tonight on ITV.
