The postponed West End revival of Hairspray the Musical starring Michael Ball and Paul Merton will now run from 22 April to 29 August 2021.
Ball returns to the role of Edna Turnblad, while Merton will make his West End musical debut as Edna's husband, Wilbur.
Ball said, "just like Edna's famous roll-on foundation, it's been a struggle but it's finally going on, and I couldn't be more thrilled. Hairspray is the perfect show to help the West End rediscover its joy, energy, talent and relevance.
"Nothing says 'we made it through' better than sitting in a theatre watching a community facing the huge social issues of their day and conquer them with the help of family, friends, commitment and love... oh, and some brilliant songs, spectacular dance routines and huge belly laughs. It's just the antidote we need. See you there."
Marisha Wallace will take the role of Motormouth and Lizzie Bea will make her West End debut as Tracy Turnblad, while Rita Simons and Jonny Amies will play Velma Von Tussle and Link Larkin respectively.
