Rubbish dances by Strictly star (5)
I believe the answer is:
balls
I believe this clue is a triple definition!
'rubbish' is the first definition.
(I've seen this before)
'dances' is the second definition.
(ball is a kind of dance)
'by' acts as a link.
'strictly star' is the third definition.

(Other definitions for balls that I've seen before include "deliveries" , "nonsense" , "Rubbish" , "Spheres, globes" , "bouncers" .)
