Pass one's life acting with Victor, Earl and the greatest boxer consumed by mischievous gossip (4,1,3)

'boxer consumed by mischievous gossip' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'pass one's life acting with victor earl and the greatest' is the wordplay.
I cannot really understand how this works, but
'one's' could be 'ive' (I've) and 'ive' is found within the answer.
'earl' could be 'e' and 'e' is found within the answer.
'the greatest' could be 'ali' (film about Muhammad Ali) and 'ali' is found in the answer.
A single letter 'l' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
