Jennifer Aniston: Over the Moon in Overalls

Jennifer Aniston is all smiles on the set of her movie, Marley and Me, at the Cardozo Hotel on Friday in Miami Beach, Florida.

Aniston, 39, shot scenes with costars Owen Wilson and Gloria Estefan.

Marley is a yellow Labrador retreiver adopted by Josh Grogan, a columnist for the Philadelphia Inquirer, and his wife. Their idea was to give them a taste of parenthood, but the dog proved to be a hyperactive handful. He wreaks havoc, gets kicked out of obedience school and gets even worse when the children begin to arrive, yet becomes an indispensable part of the family.

Marley & Me is set to open Christmas Day 2008.
