A welcomed addition.

Irish actress Denise McCormack joined EastEnders last night, much to everyone's delight. Denise is best known for her roles in Love/Hate and RedRock. She also took part in the first series of Dancing with the Stars last year on RTÉ. Now, she's just landed herself a role on one of the biggest shows in the UK. She has been introduced to Albert Square as Aidan's ex-wife Ciara Maguire and made her debut on last night's show.

It looks like Mrs Maguire is known to the police already?!? pic.twitter.com/P7Y6VAuhye

So I'm watching #EastEnders & @denisemcactress has just appeared on screen, I don't know what character she's playing but @RedRockTV3 fans like me will know it'll be a bloody good one. What a great addition to the cast, she's a brilliant actress. @redrockire
