Jennifer Aniston is living rent free at Gloria Estefan's Miami, Florida palatial estate while she films new movie MARLEY + Me. Estefan `rents' out guest houses on her $10 million (GBP5 million) Star Island retreat, and the former Friends star is living in the one where the Latina pop superstar's late mother once lived. An insider tells America's In Touch magazine, "It's (estate) typically not rented out, but close friends are welcome."
