The 45-year-old actress was spotted emerging from a lunch at Freds at Barney's with fiance Justin Theroux in a navy coat with a bag on a "fuller-looking" waist, the New York Post reported.

She was also seen out and about in Manhattan the next day clutching the same handbag close to her body.

Aniston and Theroux got engaged in 2011.
