The Wanted actress was reported this week (begs25Nov13) to have paid $20 million (£13.3 million) to buy Petra Island in New York as a gift for her longtime beau, who celebrates the age milestone on 18 December (13).
Jolie was allegedly drawn to the secluded location because it boasts two luxurious properties designed by renowned architect Frank Lloyd Wright, whom Pitt is a great admirer of.
Owners Joseph and Barbara Massaro placed the island up for sale four months ago, but they have not received any offers - let alone from the superstar.
Their daughter, Donna, tells the New York Post, "I don't have any idea where that (report) came from. The family threw it out there (put it up for sale) to see if anyone was interested, and so far no (potential buyers) have (come forward).
Jolie has previously splurged her millions to spoil Pitt on his birthday - she allegedly purchased a waterfall in California in 2011 so the actor could build his dream home around it, just like the Fallingwater property Lloyd Wright built on a similar piece of land in Pennsylvania in 1939.
