Alli Sims is just the latest person in Britney's life to exploit her for profit.
Sources reveal exclusively to PerezHilton.com that Spears' "cousin" and former assistant is speaking exclu$ively in the new issue of Us Weekly.
And, we're told she got paid A LOT of money for her little tell-all.
$200,000.00 an insider tells us.
Lynne Spears probably brokered the deal!
Update: Sources at Us Weekly tell us they "100% did not pay for this story."
Alli is friends with one of the reporters at the magazine, and that friendship is what prompted her to speak - not money.
