Average former England goalie escorting international socialite (5,6)

'socialite' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'average former england goalie escorting international' is the wordplay.
'average' becomes 'par' (average score in golf).
'former england goalie' becomes 'shilton' (I can't justify this - if you can you should give a lot more credence to this answer).
'escorting' is a charade indicator (letters next to each other).
'international' becomes 'i' (abbreviation eg in IMF).
'shilton' put after 'i' is 'ishilton'.
'par'+'ishilton'='PARIS HILTON'

Can you help me to learn more?
