Some things go together naturally, and Jennifer Aniston and little black dresses are one such pair. The former Friends star showed off her famously fit physique at a Self magazine event on Tuesday, Apr. 30, promoting Mandy Ingber's new book Yogalosophy.

The 44-year-old stunned in her LBD, which featured a deep V-neck cut and an empire waisted-silhouette that accentuated her narrow waist and toned legs.

The actress topped off her look with strappy heels and her signature hairstyle: locks worn down and blown-out. An eyewitness tells Us that she looked "comfortable and at ease" as she mingled with fellow event-goers, including Friends pal Courteney Cox.

As reported in this week's issue of Us Weekly, Aniston and fiance Justin Theroux have apparently decided to push back their nuptials so as not to overlap with ex-husband Brad Pitt's own wedding to Angelina Jolie this summer.

"She does not want her day associated with them," an insider told Us about the couple's deception. "Nothing has happened on that front in a month."

Aniston and Theroux began dating shortly after costarring together in 2012's Wanderlust, and Theroux popped the question on his 41st birthday last August after more than a year of dating.
