Argent made the confession to Digital Spy earlier this month, describing Henderson as "lovely" and "amazing", but accepting that at 16 she is "way too young".
When DS informed Henderson of Argent's feelings following her X Factor departure on Sunday (November 18), the teenager scoffed and stated: "I don't think he's got a crush on me, no. No!
"He's a funny guy and he shaved all his hair off so I call him the hamster. No, he's a really nice guy and he sings himself as well so I think it's just something he related back to me. He looks at me like I'm a little sister."
Asked if she would invite Argent to collaborate with her, Henderson replied: "I'm sure we'll be singing on a karaoke at some point."
Henderson added that it is not just Argent, but all of the TOWIE gang, that have a soft spot for her.
"The TOWIE cast are all massive fans of mine and they're all tweeting me all the time," she said.
"I think I'm actually invited to a TOWIE party over in December so I can't wait to meet them all properly and have a night with them all, it would be fun."
Henderson also told Digital Spy that she is relieved to have left The X Factor.
