Chris has been receiving treatment for a brain tumour in recent weeks, but has since started pretending that his prognosis is poor in a bid to win back his ex-partner Cheryl (Holly Quin-Ankrah). In reality, the builder has been told that the signs are looking good for his recovery.
Thorp told Soaplife of his alter ego's scheming: "I think it's horrendous. His behaviour is totally disgusting. But Chris lies so easily he doesn't really consider it to be a bad thing. And if the lie leads to him and Cheryl getting back together, so be it."
He continued: "Chris's brain tumour has strangely united Chris and Cheryl. She has been his main support throughout his illness, right from the first diagnosis really. It has brought his family back together again.
"Chris, Cheryl and Russ are all getting along well and Chris doesn't want to jeopardise that by revealing that his tumour is responding well and that his prognosis is now positive."
However, things start to go wrong for Chris in a forthcoming episode when Cheryl insists on joining him as he receives his next set of test results.
Thorp added: "He panics. Whether he gets away with his lies and gets what he wants - Cheryl - remains to be seen. He knows that if the truth is revealed, he risks losing her."
Reports have revealed that Chris, Cheryl and Russ will all be leaving Coronation Street later this year.
