Jennifer Aniston and Justin Theroux Shop at Barneys

Jennifer Aniston and Justin Theroux went shopping at Barneys New York in Beverly Hills yesterday. The couple browsed the perfume section and left the department store with a bag in hand. Jennifer and Justin already got started on their holiday celebrations after throwing a tree-trimming party at their LA home last weekend. It was a star-studded event with pals Demi Moore, Tobey Maguire, and Ben Stiller in attendance. The engaged duo had an eventful year — check out Jennifer and Justin's memorable 2012 in pictures — but it doesn't look like a baby is in their immediate future since Jen's rep shot down the latest pregnancy rumors earlier this week.
