Speaking to Chris Moyles's Radio 1 show, the 'Call My Name' singer said: "I watch it. Honest to God it's like unbelievable viewing.
"It's addictive. Charlotte is my favourite. It's fascinating... You can't not watch though. It's a guilty pleasure."
She continued: "I Sky+ them. Geordie Shore, when I watch that it makes me feel like I have familiar accents and I can go to sleep. Is that weird?"
Moyles teased Cole about potentially appearing on the show, joking: "It would be interesting to put you in that house and see how long it took you to go back to Geordie girl, proper Geordie girl, sweat pants, eating a bowl of cornflakes in the morning going, 'I hate her, I absolutely hate her'."
Cole replied: "I was just doing that this morning Chris, in my sweat pants and a bowl of cornflakes. Going to the supermarket in your pyjamas and all that."

"I think it's fair to say we all love Cheryl Cole, like any girl in the North-East for that matter. We see her as a great role model and a great ambassador for the area. She's strong. She's successful, what's not to love about Cheryl Cole?" said Vicky Pattison.
Geordie Shore is returning in the summer with a holiday special in Cancun.
