'I still get Google alerts about the other Joan Collins - usually something to do with water'
She's described her political leanings as "conservative - circa 1940s".
Small wonder then, that 'The Bitch' herself, Joan Collins, is getting a little fatigued about being connected with TD Joan Collins - a paid-up member of the United Left Alliance.
"Joan Collins is a common name - so it happens quite a lot," the 82-year-old soap star told an audience at the Newbridge Museum of Style.
"But I still get Google alerts about that Joan Collins, and something to do with water."
The former Dynasty star was mortified last year when she was mistaken for the other Joan Collins at a water protest in Dublin's Harold's Cross.
"No I am not the Joan Collins who was arrested yesterday at a Dublin protest meeting!" Collins exclaimed at the time. "The very idea!"
The two women in question live vastly different lives; one is an acclaimed actress who shot to fame playing diva Alexis Carrington in the 1980s hit TV show 'Dynasty'.
The other is a former An Post clerk from Dublin's north inner city, and a left-wing political activist. There is also the small matter of a 30-year age gap between the two ladies.
Dame Joan Collins was in Ireland yesterday with her fifth husband, Percy Gibson, to unveil her costume collection at Newbridge's Museum.
Collins refused to discuss the death of her late sister, Jackie Collins, but did chat about her plans to shoot a 'Thelma and Louise'-style movie in Ireland. The film will star Pauline Collins and Franco Nero.
"It's called 'The Time Of Their Lives'. We're very excited about it. It's a buddy movie about older women.
"A 'Thelma and Louise' for the next generation," she said.
Collins also discussed the fickle nature of the film industry. "It's a perilous profession and it's particularly difficult for young actresses getting started," she said. "But there are wonderful older women like Judi Dench and Helen Mirren who are getting roles." The actress cited Liam Neeson as one of Ireland's most attractive film stars.
