The 36-year-old actress portrayed superbitch Tanya Turner in the ITV1 drama, which she starred in for five series between 2002 and 2006.
"There isn't a day goes by that someone doesn't want to talk to me about Tanya, but that feels like a privilege still," she told Radio Times.
"At some point, everyone accepts there are certain roles that people want to cast you in, and I'm happy that mine are roles in which I get to wear fantastic frocks and, more importantly, play strong, determined women," the star added.
Lucker now plays Max Branning's love interest Vanessa Gold in BBC One soap EastEnders.
