Paul McCartney is said to be worth somewhere near $700 million, which seems a little low for me. What's his net worth? I don't know, but as they most famous -- and technically "only" living... -- member of The Beatles (Sorry, Ringo, but, you get it, right?), he may be worth closer to $1 billion. But, that's not why we're here.
McCartney has attended a few Brooklyn Nets games over the years, and most famously was upset when two seasons ago he did not catch a free t-shirt thrown his way by one of the Brooklynettes.
