The 40-year-old actress will make her debut on the BBC One soap as businesswoman Karin Smart next Thursday (09.04.15) and has promised there is "fun" things ahead for the character.

She said: "[She] is really fun and she is a bit naughty, surprise surprise. She is going to go into the Square and stir things up a little bit and I grabbed the chance to play her.

"I said if I was ever going to do ['EastEnders'], the two sort of personas you want is either to be the bitch or to be a bit of a slut. I chose to be a bit of a slut because you want a character you can have fun with.

"There is also a bit of history there with Phil Mitchell (Steve McFadden) so there definitely will be some fireworks."

Denise also praised the "brilliant" acting and says the soap is full of the "hardest working actors" around.

Speaking on Channel 4's Alan Carr: Chatty Man, she said: "The acting is so good. You only have to look at the live episodes to see how brilliant it was. And they are the hardest working actors.

"I do a lot of theatre and to walk into something like that where you have little time to learn a script. You also shoot scenes out of sequence and it can be very dramatic and you have to whizz over to another set. They work so hard. I would say they are the best actors."
