British pop star Antony Costa is set to reprise his role as Nikos in Mamma Mia! The Party, London’s premier theatrical dining experience, for a limited run until 4 September 2025.
Costa, best known as a member of the BRIT Award-winning boyband Blue, will appear in select performances at The O2, bringing his signature charm back to the immersive ABBA-themed celebration.
Joining Costa from 19 June are seven new cast members: Marianne Benedict (Matilda) as Kate (at certain performances), Paola Fareri (The Lion King) as Konstantina, Natalie Winsor (A Midsummer Night’s Dream) as Debbie, Rebecca Stenhouse (Grease) as Nina, Cameron Gabriel (Becoming Nancy) as Ruben/Swing, Stuart MacIver (Wicked) as Robin/Swing, and Nathan Shaw (White Rose) as Carlos/Swing.
They join a vibrant ensemble including Kimberly Powell as Kate (at certain performances), Henryk Firth as Adam, Oscar Balmaseda as Host/Fernando, and Dawn Spence as Grandma, among others.
Antony Costa said:
“I’m so happy to be coming back to Mamma Mia! The Party for a short stint – when they asked me I couldn’t say no, I loved it and the whole team so much. I’ll be doing this as well as touring with Blue so I’ve a busy few months ahead of me!”
Since opening in August 2019, Mamma Mia! The Party has welcomed over 600,000 guests and delivered more than 1,400 performances, drawing audiences from 110 countries.
Set in a taverna on the Greek island of Skopelos, the experience combines a four-course Greek feast with a heartwarming story and a post-show ABBA disco, featuring hits like Dancing Queen, Waterloo, and Mamma Mia.
