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

I believe the answer is:

paris hilton

I'm a little stuck... Click here to teach me more about this clue!

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

'average former england goalie escorting international' is the wordplay.
'average' becomes 'par' (average score in golf).
'former england goalie' becomes 'shilton' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'escorting' means one lot of letters go next to another.
'international' becomes 'i' (abbreviation eg in IMF).
'shilton' after 'i' is 'ishilton'.
'par'+'ishilton'='PARIS HILTON'

Can you help me to learn more?
