The actress plays Dawn Swann, who arrived in Albert Square last week when her brother Mickey brought her over to the UK from France, to be reunited with her mother Rosie.
"I love playing Dawn," Kara told The Mirror. "She's so flirty and confident - nothing fazes her and she knows how to flutter her eyelashes and make the men do whatever she wants.
"But I find it quite embarrassing to be labelled a sex symbol. I suppose it's flattering but I don't see myself like that."
She added, "I've always been cast for quite sexy roles which does sometimes make me feel more self-conscious about my figure. My character has a boob job so I've been wearing gel-filled padded bras and chicken fillets.
"It looks like I'm going to have to wear them for good unless I have a real boob job. It's not something I'm considering at the moment but you should never say never."
