And he filmed the surprise appearance in March!
The residents of Albert Square are in for a treat this spring as multi-award winning singer, actor and this year's Eurovision hopeful, representing the United Kingdom, Olly Alexander, will arrive in Walford for a surprise visit.
Having been rehearsing nearby, Olly will make a pit-stop at The Queen Victoria to reconnect with old friend Johnny Carter, where he'll be given a hero welcome by Walford well-wishers ahead of his impending performance at the Eurovision Song Contest on Saturday 11th May.
In true EastEnders style, Olly’s visit to the Square is not the only surprise of the night, as one Walford resident decides to pop the question having been buoyed up by the celebratory tone of the occasion. However, the identity of the couple in question and the all-important answer is yet to be revealed.
Speaking about his guest-appearance, Olly Alexander said "I’m thrilled to be making my first appearance on EastEnders and in the most iconic pub in the UK. I’m so happy I got to meet some true screen legends and spend time on set with the brilliant cast and crew. I wanted to surprise my mum as it’s her favourite show but I guess the cat is out of the bag now, she’s gonna love it!"
To which the soap's Executive Producer, Chris Clenshaw added "When we discovered that Olly Alexander was a huge fan of the show and an opportunity arose in one of our stories, it was the perfect moment for us to invite him to Albert Square to appear. We hope the audience enjoy Olly’s special guest-appearance as much as everyone at EastEnders enjoyed having him in Walford."
