Visitors to Burnley town centre could not help but smile after a shopper ditched her bags and broke into an impromptu dance routine on Saturday.
And the mystery lady was quite happy to be filmed by Colne teacher David Cross.
He later shared the clip on social media and it clocked up 9,544 views and 113 shares.
David said: "She was quite happy to be filmed and it really was a breath of fresh air seeing her.
"She uplifted my spirits and just seeing her like that put a smile on my face."
The clip shows the woman dancing to music which was being played by a street performer close to McDonald's restaurant.
*Do you know who the lady is who has found instant fame? Or are you the lady who has all the moves?
