Lived it up, being famous (10)
I believe the answer is:
celebrated
This clue is a double definition.
'lived it up' is the first definition.
'famous' is the second definition.
('celebrated' can be a synonym of 'famous')
'being' is the link.
(Other definitions for celebrated that I've seen before include "Notable" , "Cheered" , "Publicly honoured" , "Rejoiced - famous" , "Did something enjoyable (to mark an event)" .)
