Nigel spoke about his new stage adaptation of the Da Vinci Code, which is touring the country this year.
The Olivier Award-winning actor is renowned for his role as Dennis Rickman in EastEnders, who he played from 2003 - 2005.
Dennis immediately made an enemy out of Phil Mitchell in his debut episode and proceeded to become a fan favourite on the soap.
He won most popular newcomer at the National Television Awards in 2003 and was awarded Sexiest Male at the British and Inside Soap Awards in 2004 and 2005.
The soap star departed EastEnders in dramatic style in 2005 when when he was murdered by Danny Moon.
He has since appeared on shows such as Downton Abbey and Hotel Babylon, in addition to working extensively in theatre.
Fans of Loose Women took to Twitter gushing over how Nigel hadn't aged a day since leaving EastEnders 17 years ago.
Nick said: "Nigel Harman has not aged a day. I remember the Dennis days so well. That was Eastenders at its best."
Richard added: "B****y hell ! Nigel hasn’t aged at all."
Donnalou commented : "Nigel Harman still got it!"
Ruth posted, alongside heart emojis: "Nigel Harman"
