The outgoing and quirky character - played 23-year-old actress Nina Toussaint-White - will make her first appearance in Walford on Friday, February 6 when her dog Sugar takes a shine to Bradley's new canine companion Gumbo, a huge St Bernard.
After losing Gumbo, a worried Bradley is relieved when Syd turns up on his doorstep with the news that she's found Gumbo in the park. Inviting her into the house for a drink, Bradley wonders whether Syd could be a potential new love match.
Speaking of her part, Nina said: "I have been a fan of EastEnders for as long as I can remember and I am extremely excited to be working on such a great show. Finding out I got the job was exciting, but standing on the Square for the first time was amazing although very surreal."
She added: "I'm looking forward to working with Charlie Clements and seeing what Syd is going to get up to."
Her previous screen appearance include Casualty and Primeval.
