9. Ricky Martin – Praia Grande, Brazil
The Puerto Rican singer-songwriter Ricky Martin reportedly splurged $8 million in 2008 on a private Brazilian island.
Reports say that Martin’s island is over 19 acres and is near Angra dos Reis.
The island even has solid protection in the form of watchtowers and cannons.
Apparently, Martin only uses the island for vacations and not as his primary residence.
