Should Justin Theroux be worried?
Jennifer Aniston seems to have fallen in love on the set of her new film, Squirrels to the Nuts – puppy love, that is!
Sporting her new wig, the actress was spotted on bended knee Wednesday making fast friends with her German shepherd costar, Remy, petting her and nearly getting licked in the face in return.
Aniston’s ease with canines comes as no surprise. The bride-to-be is mom to dog Sophie, whom she rescued in 2012, and a white German shepherd named Dolly. Her beloved Welsh corgi-terrier mix, Norman, passed away in 2011 at age 15.
