Supermodel is clingy type a Rolling Stone avoids (4)
I believe the answer is:
moss
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for moss that I've seen before include "Small flowerless green plant without proper roots" , "Veteran racing driver" , "Small flowerless plant(s)" , "Supermodel Kate, b.1974" , "Clear < tiny plants" .)
