Dancing queen, Kristina Rihanoff, led over 100 girls from Stagecoach Theatre Arts in a flashmob in Brighton on Sunday.
"It's a perfect day for a summer dance!" she tweeted. "Come along and join in if you are near…"
The Strictly Come Dancing star joined LEGOFriends and the girls from Stagecoach to celebrate the premiere of new Disney hit Teen Beach Movie as well as the summer holidays.
The unexpected scene in Brighton saw the dance troupe fill the famous pier to recreate a routine from the new Disney film.
Kristina was said to be very excited to join in the dancing and be in Brighton.
Teen Beach Movie aired on the Disney Channel on 19th July. It is described as the next High School Musical and a summer smash hit.
