James headed over to the X Factor studios this weekend to show his support for the finalists as they sang live for the second time on Saturday night (19 October).
But despite telling host Dermot O'Leary that he is a fan of Kingsland Road and Rough Copy during Saturday's live show, James appears to have a female favourite in the competition.
The Middlesborough born singer was pictured cuddling up to Tamera Foster in a cute snap that she then uploaded to her Twitter this weekend.
Tamera, 16, also tweeted: "Just met the amazing @JamesArthur23."
And James' telling response appears to give away who he really is rooting for on X Factor this year, as he simply replied to Tamera with an open mouthed and stunned-looking emoticon - twice!
Last week, James - who was also mentored by Nicole Scherzinger during his time on the show - revealed that he thought Tamera had the total package and even compared her to superstar Rihanna!
He said: "... She's a beautiful looking girl - she's got a great voice. She's like a better looking Rihanna."
The girls category this year is a tough one, as Tamera will have to fight off competition from unique talent Abi Alton and power-ballad pro Hannah Barrett.
All three girls sailed through to next week's live show, but it wasn't all smiles backstage, as Abi was swiftly rushed to hospital on Sunday night (20 October) after falling down a set of stairs.
She has since returned to The X Factor house and reassured her fans she is fine by tweeting: "Out of hospital and thankfully there is no serious damage. Thanks for your lovely messages, im sure will be right as rain in no time xxx"
