The brunette reality star told us: "Nathan is obsessed him, Nathan wants to watch him in court, he loves him! We watch it everyday; if we're at home we have to watch it."
The current series of Judge Rinder airs weekdays at 2pm on ITV.
Cara told Reveal that Nathan even has Judge Rinder's famous shushing catchphrase down to a fine art!
"Nathan comes up to me and goes 'shh shh shh' but if I didn't know where it was from I would be like, 'Why you doing that?'" she laughed.
Of course, that means the couple are loving Judge Rinder on Strictly Come Dancing!
Cara's already told Reveal she dreams of being invited on the show one day, but for now she's content cheering on the celebrity contestants.
"I'm friends with Melvin and he went the first week. Me and Nathan were tweeting him like ,'Good luck, Melvin! Smash it!' He's so nice."
"I like Danny Mac," she told us. "I don't know how he's not a professional! I love Danny Mac I think he's amazing. I think that he looks like Nathan, he's got the same jaw line, the same eyes, the same cheeks. Every time I see him I go, 'That's Nathan!'
"I'm obsessed! I would love to be on Strictly!" she added.
"I would die, like I could die happy if I did Strictly!"
Cara spoke to us at the Sistaglam and Jessica Wright Collection Launch.
