Jennifer Aniston Mixes Business and Pleasure at a Smartwater Photo Shoot in LA

All eyes were on Jennifer Aniston as she posed for a Smartwater photo shoot in LA on Tuesday. The actress was spotted wearing a floor-length, low-cut black-and-white gown while getting primped by her hairstylist, Chris McMillan, stylist Leslie Fremar, and makeup artist Gucci Westman. While working on the photo shoot, Jen also helped celebrate her long-time friend Gucci's 45th birthday. The makeup artist shared a photo to Instagram of herself being presented with a cake by Jen and Leslie, writing, "Thank you for my cake ! Spending my birthday with my great old pals."

Jen has stayed relatively low-profile these past few months, but her husband, Justin Theroux, hasn't shied away from speaking out on her behalf. While promoting The Girl on the Train earlier this month, the actor revealed that he doesn't mind being referred to as Mr. Jennifer Aniston, saying, "It doesn't really get under my skin. It's just one of those things that's a shorthand for describing who I am," and praised his wife for being a "proper badass." "She has lived through a lot of bullsh*t," Justin told The Sunday Times, adding, "Many people would have crumbled under some of the stresses that have been put on her. I'm very proud of her for that, for the way she handles herself."
