Sir Paul McCartney
Here Comes the Sun ...
And Lots of SPF!
BY TMZ STAFF
Paul McCartney got a little help from his friend/wife while roasting in the sun.
Paul and Nancy Shevell have been chilling in Ibiza ... where most people are capable of applying sunscreen on their chests without assistance -- but most people aren't Beatles and Knights.
Sure ... 53-year-old Nancy might look kinda like a nursemaid lathering ointment on a patient -- but we're guessing rubbed up 72-year-old Paul ain't complainin'.
In case you forgot ... it's good to be a Beatle.
