The island, called Petra, also contains two houses that were designed by famed architect Frank Lloyd Wright, a personal favorite of Pitt's.
"As soon as Angelina heard the island was on the market she arranged a viewing. She was really impressed," a source told the U.K.'s Mirror. "The house is perfect for romantic getaways or as a family retreat. It's very private. And Angelina knows the fact the island is in the shape of a heart will mean so much to him."
This isn't the first extravagant Frank Lloyd Wright-themed present Jolie has purchased for Pitt. In 2011, Jolie purchased a California waterfall and the land surrounding it for Pitt's birthday, so they could construct a home on it in homage to Fallingwater, Wright's most famous structure.
Petra is 11 acres, has a helicopter pad, and features a Wright-designed cottage built in 1950 and a main house that was built in 2008 based off Wright's plans. Jolie reportedly purchased it for approximately $24 million.
