according to mediamass.net:
The English singer-songwriter-musician has an estimated net worth of $275 million. She owes her fortune to smart stock investments, substantial property holdings, lucrative endorsement deals with CoverGirl cosmetics. She also owns several restaurants (the “Fat Harvey Burger” chain) in London, a
Football Team (the “Bridport Angels”), has launched her own brand of Vodka (Pure Wonderharvey - England), and is tackling the juniors market with a top-selling perfume (With Love from PJ) and a fashion line called “PJ Harvey Seduction”.
lol the site is totally bizarre and includes other headlines such as "PJ Harvey dead at 44" and "PJ Harvey nude pics leak"

i think it's satire of some kind, though not especially funny.
