The model-turned-bodybuilder drummed up support for the X Factor contestant on her Twitter page over the weekend.
"Catching up on last nights #XFactor and I am falling more & more in love with @JamesArthur23 not just for the singing either #majorcrush," Marsh wrote, adding that she would like Arthur to "come to mine and sing to me and we can compare tattoos all night... hehe".
She also encouraged her followers to cast votes for the 24-year-old singer, telling him: "You are beautiful. Inside and out."
Arthur responded to her first post, writing "I love you too Jodie Marsh! Anytime," leading Marsh to quip: "He sings. He has tattoos. He loves me. He's perfect."
The X Factor continues this Saturday (October 13) on ITV1.
