Sande performed on The X Factor stage last Sunday with Labrinth, and met James backstage after his rendition of LMFAO's 'Sexy and I Know It.'
The 'Read All About It' singer now appears to be a fan of his, telling the Metro: "I really like James Arthur.
"I haven't watched too much but I definitely saw his performance at the beginning. He just blew me away."
She went on to say that she'd like to work with him, adding: "I met him at the weekend and I'd love to get in the studio with him. I think he'd be great. He's brilliant."
However, Sande went on to say that she would never have considered being a contestant on the reality show, citing nerves as a reason not to.
She explained, "I think I'd try any other route than doing it. I couldn't face going on that stage every week, it's nerve-wracking."
James Arthur: could a duet with Emeli Sande be in the works?
This is big praise coming from Sande, who recently won a much coveted Q Award for Best Solo Artist.
She was quoted in the Daily Record as saying, "This is a big one. It's a big competition, so it was really good. I'm very happy about this.
"It feels really nice to get that type of acknowledgement."
Sande also begins a sold out tour next month, including dates at the Royal Albert Hall and Manchester Bridgewater Hall.
