Star and singer getting MDMA for party (9)
I believe the answer is:
celebrate
'for party' is the definition.
(I've seen this before)
'star and singer getting mdma' is the wordplay.
'star' becomes 'celeb' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'singer getting' becomes 'rat' (I can't justify this - if you can you should give a lot more credence to this answer).
'mdma' becomes 'E' (MDMA is ecstasy, ie 'E').
'celeb'+'rat'+'e'='CELEBRATE'
Can you help me to learn more?
(Other definitions for celebrate that I've seen before include "Publicly praise (someone)" , "Honour; make famous" , "Mark an important occasion with festivities" , "Mark an occasion with a social gathering" , "Stage a special festivity" .)
