With The X Factor USA's live finals set to kick off tonight (October 31), it's Britney Spears who is the clear frontrunner to be the winning judge in a few weeks' time.
Over the next couple of months, the Final 16 will be whittled down to one eventual winner, and Spears' act Carly Rose Sonenclar is the bookies' favourite with bet365, with odds of 11/4.
Diamond White, also mentored by Spears, is the second favourite on 9/2.
Demi Lovato's Willie Jones (13/2), Jennel Garcia (9/1) and CeCe Frey (9/1) follow to complete the Top 5 frontrunners.
Simon Cowell's top contenders are girlband LYLAS and LYRIC 145, both on 10/1.
LA Reid's Vino Alan is on 12/1, along with boyband Emblem3.
Beatrice Miller (15/1), Tate Stevens (16/1), Arin Ray (20/1), Paige Thomas (28/1), David Correy (33/1), Sister C (33/1) and Jason Brock (40/1) complete the list.
Spears is 5/6 favourite to be the winning manager. Lovato and Cowell are tied on 4/1, with Reid on 9/2.
It had been rumoured earlier in the filming process that Lovato had orginally been handed the Teens category, and Spears the Young Adults category. However, producers allegedly switched the two round, knowing that the Teens category had more potential winners... and that Spears' contract is worth $14 million more than Lovato's.
